Docket No. 275518.
Court of Appeals of Michigan.

Decided July 10, 2008, at 9:00 a.m.
*115 Lawrence J. Acker, P.C. (by Lawrence J. Acker), Bloomfield Hills, for the plaintiff.

Before: SAAD, C.J., and BORRELLO and GLEICHER, JJ.
SAAD, C.J.
In Mr. Rickie Wright's legal-malpractice action against his lawyer, Ms. Amy Rinaldo, the trial court granted summary disposition to Rinaldo and her law firm[1] because Wright failed to file his complaint within the applicable two-year period of limitations. For the reasons set forth in this opinion, we affirm the trial court's holding that plaintiff's malpractice claim is time-barred.

I. NATURE OF THE CASE
Under Michigan's statutory law, a client's claim against his or her attorney for professional malpractice accrues on the date that his attorney "discontinues serving *116 the plaintiff in a professional ... capacity as to the matters out of which the claim for malpractice arose...." MCL 600.5838(1). The client's action for malpractice is time-barred unless it is brought within two years from the date the claim accrued or arose (i.e., the date that services were discontinued), or within six months of the date that "the plaintiff discovers or should have discovered the existence of the claim," whichever date occurs later. MCL 600.5805(6); MCL 600.5838(2); Kloian v. Schwartz, 272 Mich. App. 232, 237, 725 N.W.2d 671 (2006). Here, the client, Wright, unquestionably knew of his lawyer's alleged malpractice before Rinaldo ceased representing him; therefore, the timeliness of Wright's filing of his complaint depends on the date that his attorney discontinued services. Rinaldo says this accrual date is December 18, 2003, when Wright in essence ended the relationship, albeit without formally informing Rinaldo. Rinaldo maintains, and we agree, that Wright effectively terminated the attorney-client relationship on December 18, 2003, when he (1) hired other attorneys to handle his patent application, (2) executed documents revoking her power of attorney, and (3) granted one of his new lawyers power of attorney to represent him in the patent-application process. The evidence also shows that Wright concealed from Rinaldo (1) his dissatisfaction with her performance, (2) his intent to sue her for malpractice, and (3) the fact that he had replaced her with other lawyers, because he needed her testimony in a related lawsuit and also because he wished to postpone the accrual date of his malpractice claim so that his cause of action would not be time-barred.
Accordingly, by virtue of Wright's actions, the attorney-client relationship ended on December 18, 2003, notwithstanding Wright's "strategic concealment" of his conduct from Rinaldo. Wright's malpractice suit was therefore untimely because he delayed filing it until February 16, 2006, more than two years after the accrual date of December 18, 2003.

II. FACTS AND PROCEDURAL HISTORY
Beginning in August 2000, Rinaldo represented Wright to prosecute his patent application and amendments for an absorbent "surface protection system mat" and, as counsel, filed various documents with the United States Patent and Trademark Office. During the summer and fall of 2003, Wright became dissatisfied with Rinaldo's work. At the time, Wright was also represented by attorney Michael Nedelman in a bankruptcy matter. Wright also intended to have Nedelman pursue litigation to enforce Wright's patent rights against his former business partner, Wade Waterman, and other companies that were marketing a surface-protection mat that was similar to Wright's invention.
By October 2003, Wright and Nedelman began to consult with another patent attorney, Arnold Weintraub, about the enforceability of Wright's patent, and Wright ultimately directed Weintraub to undertake all the legal work for the patent. To this end, on December 18, 2003, Wright met with Nedelman and Weintraub and signed a document issued by the patent office that revoked Rinaldo's power of attorney. At the same time, Wright executed a power of attorney for Weintraub and instructed the patent office that all future correspondence should go to Weintraub. The power of attorney authorized Weintraub to prosecute the patent and "to transact all business in the United States Patent and Trademark Office connected therewith." On the same day, Wright also signed an affidavit that Nedelman notarized. It appears that the affidavit was drafted in an effort to remove Waterman's name from Wright's floor-mat patent. In this affidavit, *117 Wright blamed the error in designating Waterman as a co-inventor on Rinaldo, whom he identified as his "previous counsel." Wright also asserted in the affidavit that he had "retained new patent counsel."
The record reflects that, after the revocation, Wright and his attorneys were reluctant to communicate with Rinaldo because they believed that Rinaldo's favorable testimony was critical to Wright's lawsuit against Waterman. Indeed, after Wright obtained the favorable testimony he sought from Rinaldo, Wright ceased all communication with her.
On February 23, 2004, Weintraub filed a "preliminary amendment" with the patent office to add new claims to the description of Wright's floor-mat invention. Weintraub signed the documents and also sent to the patent office the December 18, 2003, documents that granted him power of attorney and revoked Rinaldo's power of attorney. The record reflects that, though no one corresponded with Rinaldo after she signed the affidavit, Wright remained concerned about Rinaldo's continuing role in providing favorable testimony in the litigation against Waterman. However, around the same time, Wright and Nedelman began to consult with attorneys about filing a malpractice action against Rinaldo. Wright also advised Weintraub that Nedelman should participate in the attorney consultations because he needed Rinaldo's testimony before they filed the malpractice action. Wright also expressed concern that the period of limitations for his claim against Rinaldo might expire.
In October 2005, Rinaldo sent Wright a letter to advise him that the maintenance fee for his patent was due on March 10, 2006. Rinaldo testified that, although she did not represent Wright as his attorney at that time, she had calendared his maintenance-fee dates and, when the date was flagged, she alerted Wright so that she would not be blamed if he allowed the patent to lapse. Rinaldo's letter further stated that, if Wright wanted her or her firm to pay the fee, he would need to pay a retainer fee in advance.[2] Wright ultimately had Weintraub pay the maintenance fee for the patent.
Later, in October 2005, Rinaldo sent another letter to Wright, indicating that she had received correspondence from the patent office that it had disallowed some claims she filed in May 2003. Rinaldo also stated that she had received notice from the patent office that her power of attorney had been revoked, and she asked for information about where to send the file. Wright was upset to learn that Weintraub had submitted the revocation of Rinaldo's power of attorney to the patent office. He wrote to Weintraub and complained that Nedelman and Weintraub had always taken the position that Rinaldo needed to remain the attorney of record with the patent office if they wanted to timely file a legal-malpractice action against her.
Thereafter, Weintraub informed Wright that had he replied to correspondence from the patent office that had been erroneously sent to Rinaldo. Weintraub wrote the following in his response to the patent office:
Kohn & Associates, Farmington Hills, Michigan prosecuted the above United States Patent 6,446,275 and on May 12, 2003 filed this reissue application. On December 18, 2003, Applicant (Mr. Rickie Wright) revoked the Power of *118 Attorney to Kohn & Associates and appointed the undersigned (Mr. Arnold S. Weintraub) as his attorney to prosecute all business associated with this matter.

Wright filed this legal malpractice action against Rinaldo on February 16, 2006. Specifically, Wright alleged that Rinaldo had (1) failed to promptly remove Waterman from the patent application, (2) improperly drafted documents submitted to the patent office, and (3) failed to recognize and take steps to correct the patent because it did not adequately protect Wright's invention. The trial court granted Rinaldo's motion for summary disposition, held that Wright and Rinaldo's attorney-client relationship ended on December 18, 2003, and, therefore, ruled that Wright's February 2006 complaint was barred under the two-year statute of limitations.

III. ANALYSIS[3]
The primary purposes behind statutes of limitations can be summarized as (1) encouraging the plaintiffs to diligently pursue claims and (2) protecting the defendants from having to defend against stale and fraudulent claims. Lemmerman v. Fealk, 449 Mich. 56, 65, 534 N.W.2d 695 (1995). In Lothian v. Detroit, 414 Mich. 160, 166-167, 324 N.W.2d 9 (1982), our Supreme Court enumerated several policy considerations underlying statutory limitations periods, including security against stale demands when circumstances would be unfavorable to a just outcome, the avoidance of inconvenience resulting from delay in asserting legal rights, and penalization of plaintiffs who have not been industrious in pursuing their claims.
Pursuant to MCL 600.5805(6) and MCL 600.5838(2), a plaintiff must file a legal-malpractice action within two years of the attorney's last day of service to the plaintiff or within six months of when the plaintiff discovered or should have discovered the claim, whichever is later.[4] The parties agree that Wright's knowledge of Rinaldo's alleged malpractice clearly preceded the last day of service and that the operative date is the date of Rinaldo's last service as Wright's attorney. The parties disagree about when that occurred.[5] "Generally, when an attorney is retained to represent a client, that representation continues until the attorney is relieved of the obligation by the client or the court." *119 Mitchell v. Dougherty, 249 Mich.App. 668, 683, 644 N.W.2d 391 (2002).[6] Retention of an alternate attorney effectively terminates the attorney-client relationship. Kloian, supra at 237, 725 N.W.2d 671. The dispositive question is when did Wright effectively terminate Rinaldo's representation of him in this patent application.
Rinaldo testified that, at a meeting on November 7, 2003, it was made clear to her by Wright, and Nedelman and Weintraub, that she no longer represented Wright as his patent counsel. Also, significantly, Wright signed the revocation of Rinaldo's power of attorney on December 18, 2003, and, on the same day, he signed another document granting power of attorney to Weintraub. As Weintraub later represented to the patent office, Wright's revocation and Weintraub's appointment both occurred when Wright signed the papers on December 18, 2003. Indeed, from Weintraub's assertions to the patent office, it is clear that he believed that he was acting as Wright's sole patent counsel as of December 18, 2003. On the same date, Wright also signed a notarized affidavit in which he referred to Rinaldo as his former attorney and stated that he had retained new counsel.
Though Wright claims that he intended Weintraub and Rinaldo to act as "co-counsel," his own actions belie this assertion. Wright would have had no reason to revoke Rinaldo's power of attorney if he had intended her to continue representing him along with Weintraub. Rather, Wright substituted Weintraub as his attorney by authorizing Weintraub "to transact all business in the United States Patent and Trademark Office connected" with his floor-mat patent. While Wright claims that mere "consultation" with another attorney does not end an attorney-client relationship, the evidence we have outlined shows that he not only consulted with Weintraub, but appointed him as his new counsel. And, though Rinaldo drafted language to correct the patent or expand its protection in November and December 2003, Wright later had Weintraub file his own changes with the patent office.
Rinaldo presented further evidence that, as early as October 28, 2003, Wright directed Weintraub to correct Rinaldo's alleged mistakes and that, by November 2003, Nedelman had determined that Rinaldo was "doing nothing of value" while he and Weintraub were reworking Wright's patent claims. In the November 24, 2003, e-mail from Wright to Nedelman, Wright asserted that he would no longer communicate with Rinaldo, and he directed that Weintraub "take charge" of the patent prosecution. Indeed, from the time Wright signed the documents on December 18, 2003, he had Rinaldo perform no work on the patent prosecutionthe very matter for which he had retained her.
Though Wright maintains that he never explicitly informed Rinaldo of her termination as his counsel or formally relieved her of her duties, his actions show that the attorney-client relationship was, in fact and law, terminated as of December 18, 2003.[7]
*120 In response to the substantial evidence that Wright discharged Rinaldo as his attorney by December 18, 2003, Wright takes the position that the rules in the Manual of Patent Examining Procedure (MPEP) determine when a claim accrues because the rules define when an attorney may withdraw from representing a client in the patent office. According to Wright, the rules state that a withdrawal or revocation does not occur until the patent office approves it. Wright cites no authority to support his claim that MPEP rules take precedence over Michigan law in determining the state-law matter of whether a malpractice action is timely. Wright merely maintains that, because the underlying case involved a patent issue, the patent office's rules should govern. However, as the trial court pointed out, the rules Wright cites only state that the withdrawal of patent counsel is effective upon approval by the patent office. The rules do not state that the revocation of a power of attorney is only effective when it is approved. Further, as Rinaldo's evidence established, Wright did not merely revoke her power of attorney, he granted the power of attorney to new counsel, Weintraub, and specifically directed him to take over the patent prosecution. Again, a formal discharge is not required to end an attorney-client relationship, particularly when, as here, a client has retained new counsel. Mitchell, supra at 682-684, 644 N.W.2d 391.
In an effort to prove an accrual date after December 18, 2003, Wright also presented evidence that, in October 2005, Rinaldo wrote to Wright to advise him that he must file a maintenance fee for his patent. Wright claims that this shows that Rinaldo saw her professional relationship with Wright as ongoing. In response, Rinaldo testified that she had calendared Wright's maintenance-fee schedule when he was a client and that she received notification in October 2005 that the fee was due. She further testified that, although she did not consider herself to be Wright's attorney, she sent the reminder letter so that she would not be blamed if the patent lapsed. Regardless of her reasoning, Rinaldo's ministerial task of sending a reminder letter to Wright did not extend the accrual date. Rather, Rinaldo's notification falls within the category of matters outlined in Bauer v. Ferriby & Houston, PC, 235 Mich.App. 536, 538-539, 599 N.W.2d 493 (1999):
A lawyer has an ethical duty to serve the client zealously. See, e.g., Grievance Administrator v. Fried, 456 Mich. 234, 242, 570 N.W.2d 262 (1997); American Employers' Ins. Co. v. Medical Protective Co., 165 Mich.App. 657, 660, 419 N.W.2d 447 (1988). Some of a lawyer's duties to a client survive the termination of the attorney-client relationship, most notably the general obligations to keep client confidences and to refrain from using information obtained in the course of representation against the former client's interests. See MRPC 1.6 and 1.9 and comments. Sound public policy would likewise encourage a conscientious lawyer to stand ever prepared to advise a former client of changes in the law bearing on the matter of representation, to make a former client's file available if the former client had need of it, and, indeed, to investigate and attempt to remedy any mistake in the earlier representation that came to the lawyer's attention. To hold that such follow-up activities attendant to otherwise completed matters of representation necessarily extends the period of service to the client would give providers of legal *121 services a powerful disincentive to cooperate with a former client who needs such attention. We conclude that the proper inquiry is whether the new activity occurs pursuant to a current, as opposed to a former, attorney-client relationship. [Emphasis added.]
Rinaldo specifically stated in her letter that, if Wright wanted her to follow up with the patent maintenance, he would have to remit a retainer fee. Further, Wright had vowed not to speak to Rinaldo and, indeed, he did not speak to her after he signed the revocation on December 18, 2003. As Rinaldo observes, Wright did not even know how to respond to her maintenance-fee letter, but feared that if he did not respond, she would "get suspicious." This conduct is inconsistent with an ongoing professional relationship between Wright and Rinaldo, particularly given that Wright had obtained different patent counsel, did not permit Rinaldo to work on any further patent matters, and had no communication with her for almost two years.
In sum, Wright's conduct clearly demonstrated that he ended the attorney-client relationship with Rinaldo no later than December 18, 2003, although he did so in a somewhat unorthodox fashion. And, because Wright failed to file his legal-malpractice complaint until February 16, 2006, the trial court correctly ruled that his malpractice claim was barred by the two-year statute of limitations.
Affirmed.
BORRELLO, J., concurred.
GLEICHER, J. (dissenting).
I respectfully dissent. Under the text of MCL 600.5838(1), plaintiff's legal-malpractice claim accrued when defendant Amy Rinaldo discontinued serving him in a professional capacity "as to the matters out of which the claim for malpractice arose, regardless of the time the plaintiff discovers or otherwise has knowledge of the claim." Rinaldo discontinued serving plaintiff in October 2005, when Rinaldo first learned that plaintiff had revoked her power of attorney to act as his patent counsel. Contrary to the majority's analysis, plaintiff's earlier knowledge of the existence of a claim is neither controlling nor relevant, according to the unambiguous language of the accrual statute. Therefore, plaintiff timely filed this lawsuit on February 16, 2006.
The majority concludes that the cause of action accrued on December 18, 2003, because plaintiff signed documents on that date revoking Rinaldo's power of attorney and referring to her as his "former" counsel. According to the majority, when plaintiff signed these documents, he "in essence ended the relationship, albeit without formally informing Rinaldo." Ante at 116. The majority acknowledges that plaintiff "strategic[ally] conceal[ed]" his intent to discharge Rinaldo and that Rinaldo had no knowledge of plaintiff's intent to discharge her until October 2005. Ante at 116.
The "matter[] out of which the claim for malpractice arose" was a defective patent application. The factual record, in conjunction with the rules governing patent law practice, establishes that Rinaldo bore the responsibility to represent plaintiff until his new counsel successfully filed a revocation of her power of attorney and Rinaldo learned of that filing. In MCL 600.5838(1), the Legislature described a purely objective standard for accrual that triggers the running of the two-year period of limitations by a discernible event: the discontinuation of services. An attorney does not discontinue serving a client merely by making a subjective mental decision to quit. In my view, communication *122 with the client is an essential element of an attorney's decision to discontinue representation. Further, I believe that an unhappy client may elect to continue an attorney's representation despite dissatisfaction with the attorney's performance or an expressed intent to discharge the attorney in the future. If the client elects to maintain the attorney-client relationship, the attorney remains responsible for the dissatisfied client's representation until he or she (1) is relieved of that obligation by the court, (2) is officially fired by the client, or (3) gives the client reasonable notice that representation has been terminated. See MRPC 1.16.

I. THE FACTUAL RECORD
In September 1999, plaintiff, Rickie Wright, and his business partner, Wade Waterman, filed an initial patent application for a "Surface Protection System Mat." Plaintiff had drafted the patent application without the assistance of counsel. In June 2000, the United States Patent and Trademark Office (USPTO) rejected the patent application for several reasons, including plaintiff's failure "to define the invention" in the requisite manner and the application's recitation of the claims "in narrative form ... replete with indefinite and functional or operational language." Plaintiff then retained Rinaldo, a registered patent specialist,[1] to file an amendment of the defective 1999 patent application. Rinaldo commenced her efforts on plaintiff's behalf by filing with the USPTO a power of attorney signed by plaintiff.
The rules of practice before the USPTO are similar to the Michigan Court Rules in several important respects. Under the Michigan Court Rules, an attorney "may appear by an act indicating that the attorney represents a party in the action." MCR 2.117(B)(1). "Act" includes filing "a written appearance...." MCR 2.117(B)(2)(a). The rules governing practice in the USPTO provide that "[a]n applicant for patent may file and prosecute his or her own case, or he or she may give a power of attorney so as to be represented by one or more patent practitioners or joint inventors." 37 CFR 1.31. The power of attorney in a patent case serves exactly the same function as an appearance:
When a patent practitioner acting in a representative capacity appears in person or signs a paper in practice before the United States Patent and Trademark Office in a patent case, his or her personal appearance or signature shall constitute a representation to the United States Patent and Trademark Office that under the provisions of this subchapter and the law, he or she is authorized to represent the particular party on whose behalf he or she acts. [37 CFR 1.34.]
On August 29, 2000, Rinaldo filed with the USPTO an amendment of plaintiff's patent. While the amended patent application was pending in the USPTO, a business owned by plaintiff and Waterman (Golden Eagle) marketed and sold the surface-protection mat. In September 2002, the USPTO approved plaintiff's amended patent.
After the USPTO approved the amended patent, plaintiff discovered that a company called St. Clair Plastics "was out there making and selling my invention without my permission...." Plaintiff brought this concern to the attention of *123 both Rinaldo and Golden Eagle's business litigation firm, Maroko & Landau, P.C. Around the same time, plaintiff's relationship with Waterman deteriorated, and Golden Eagle sought bankruptcy protection.
On May 12, 2003, at plaintiff's request, Rinaldo filed a "reissue application" to "correct inventorship" by removing Waterman's name from the patent as a coinventor. This act continued Rinaldo's representation of plaintiff regarding the defective patent. At that point, correction of the patent to remove Waterman's name constituted the matter about which Rinaldo represented plaintiff as his patent counsel.
On July 9, 2003, plaintiff sent Rinaldo an e-mail stating:
Michael Nedelman is a new lawyer being added to assist Maroko and Landau in my defense of the patent and any offensive action I may need to take. Michael is well known and respected in the courts. Michael is taking a lead role in the bankruptcy court regarding the termination of my patent license to Golden Eagle as well as other matters....
Would you please give him a brief call or send him an e-mail regarding the patent[?]
According to her billing records, Rinaldo met with plaintiff on July 28, 2003, regarding "litigation," reviewed documents drafted by an attorney concerning "related litigation," and forwarded "comments regarding the same to attorney."
On September 5, 2003, Nedelman wrote to Rinaldo and requested more information about the patent. His letter read: "I need some guidance from you in connection with the anticipated institution of suit against potential infringers upon the patent held by Rickie Wright. Since I have no patent experience, I read the patent as approved by the Patent Office." (Emphasis in original.) Rinaldo e-mailed plaintiff on September 17, 2003, and advised that "we should add a few new claims...." The email continued: "[P]lease let me know how you wish to proceed. I will be out of the office until Monday, but I can begin working on the new claims first thing Monday morning."
Plaintiff, Nedelman, and Rinaldo met on September 23, 2003. On October 14, 2003, Nedelman spoke with another patent attorney, Arnold Weintraub, regarding correction of the inventorship issue. Three days later, Nedelman wrote to Rinaldo to express concern about the progress of the efforts to remove Waterman's name from the patent. Nedelman also criticized "the efficacy" of Rinaldo's attempts to remove Waterman "as an inventor" and expressed concern about the patent itself:
You have recently admitted that the claims you prepared failed to adequately describe and do not encompass the actual product designed by Rickie Wright, and as being manufactured and sold. The failure to advance the correct claims, coupled with your earlier misrepresentations to Rickie Wright that the product was protected, has caused Mr. Wright to suffer significant damages including, but not limited to, lost profits/royalties, the legal fees and expenses paid to your firm, and the costs anticipated to be incurred in rectifying your errors and omissions.
The situation must be rectified, and your errors and omissions corrected to the fullest extent possible. Mr. Wright must be compensated for the damages he has suffered and, if your errors and omissions cannot be corrected, for the damages he will continue to suffer. Please immediately advise me of the course of action you intend to take.
*124 When she received this letter, Rinaldo could have communicated to plaintiff and Nedelman her intent to withdraw as plaintiff's counsel in the patent matter. Alternatively, plaintiff could have fired Rinaldo and instructed Weintraub to file a power of attorney with the USPTO. Instead, Rinaldo responded to Nedelman on October 29, 2003, asserting that "the removal of Wade Waterman as an inventor is being handled properly and in accordance with USPTO practices." Rinaldo concluded:
Finally, and most importantly, please be aware that the written opinions you expressed in your letter of October 17, 2003, could be grossly prejudicial to Mr. Wright's position. In the future, Mr. Wright's interests are best served by telephoning our office to seek clarification of any issues that may be confusing to either you or Mr. Wright. [Emphasis supplied.]
Rinaldo wrote the following to plaintiff on the same day:
I have responded to Mr. Nedelman's letter of October 17, 2003. Please be aware that the written opinions expressed by Mr. Nedelman in his letter could be grossly prejudicial to your position. In the future, your interests are best served by telephoning our office to seek clarification of any issues that may be confusing to either you or Mr. Nedelman. [Emphasis supplied.]
Rinaldo met with Nedelman, plaintiff, and Weintraub on November 7, 2003, and prepared the following "Memorandum of Understanding" summarizing their discussion:
At a meeting held Friday, November 7, 2003, it was agreed among all parties present that Nedelman and/or Weintraub will draft, file, serve and prosecute to finality a civil action lawsuit on behalf of Rickie Wright against Wade Waterman.
It was further agreed among all parties present that Rinaldo will draft and file an amendment consistent with the claims presented at the meeting by Weintraub.
Later that month, plaintiff e-mailed Rinaldo to "check in and make sure you, Michael, and Arne [Weintraub] are working toward a correction of the problems we discussed regarding the patent and it's [sic] claims." The e-mail concluded, "Please let me know if you have any questions or if I can help in any way." On November 26, 2003, Rinaldo replied: "The week after we met I sent the correction to Arnie [Weintraub]. I am waiting for him to tell me to file the amendment." On December 3, 2003, Rinaldo e-mailed the proposed amendment to Weintraub, along with a USPTO form entitled "Reissue Application Declaration By The Inventor," which listed Rinaldo and her law firm as plaintiff's counsel after the language "As a named inventor, I hereby appoint the following attorney(s) and/or agents to prosecute this...."
On December 18, 2003, plaintiff signed a document revoking Rinaldo's USPTO power of attorney and executed the affidavit discussed by the majority, which referred to Rinaldo as his "previous counsel." Despite signing these documents, plaintiff deliberately refrained from instructing Weintraub to file the documents or discharging Rinaldo as his patent counsel. On January 9, 2004, Rinaldo signed an affidavit averring that Waterman had "made no contribution to the invention of the surface protection mat" and had been "inadvertently and erroneously identified as a co-inventor" in the patent application. On January 21, 2004, plaintiff sued Waterman in federal court, seeking a declaration that Waterman had no legally cognizable interest in the surface-protection-mat patent.
*125 In February 2004, Weintraub mailed to the USPTO the preliminary patent amendment prepared by Rinaldo, as well as the signed revocation of her power of attorney. The parties agree that, for unknown reasons, the USPTO never acknowledged receiving these documents and did not act on them. According to Weintraub, a patent examiner eventually told him that the February 2004 filings had "fallen into a black hole...." Weintraub resubmitted the materials in September 2005, and the USPTO finally processed them on October 20, 2005.
Meanwhile, however, the amendment submitted by Rinaldo in May 2003 remained pending in the USPTO. On October 17, 2005, the USPTO announced its decision regarding the patent amendment by sending Rinaldo, the attorney of record, an "Office communication concerning this application or proceeding," which informed Rinaldo that the USPTO had rejected "Claim(s) 1-8" of the May 12, 2003, patent reissue application. A clerk at Rinaldo's office wrote on the USPTO transmission document: "Response 11-17-05."
Rinaldo admitted at her deposition that she had never sent plaintiff a communication reflecting her intent to withdraw as his patent counsel. She additionally conceded that plaintiff had never advised her that he had "fired" her; she merely assumed that he had done so because of the "tone" of their November 7, 2003, meeting with Nedelman and Weintraub. Nor did Rinaldo make any effort to withdraw as plaintiff's patent counsel, pursuant to the clear provision of the patent rules providing: "A registered patent attorney or patent agent who has been given a power of attorney pursuant to [37 CFR 1.32(b)] may withdraw as attorney or agent of record upon application to and approval by the Director." 37 CFR § 1.36(b) (emphasis supplied). This rule bears a substantial similarity to MCR 2.117(C)(2), which provides that "[a]n attorney who has entered an appearance may withdraw from the action or be substituted for only on order of the court."

II. APPLICATION OF THE LAW
The majority's decision to affirm the trial court's grant of summary disposition is premised on its determination that "the attorney-client relationship was, in fact and law, terminated as of December 18, 2003," the date that plaintiff signed the revocation of the power of attorney. Ante at 119. According to the majority, plaintiff "ended the attorney-client relationship with Rinaldo no later than December 18, 2003, although he did so in a somewhat unorthodox fashion." Ante at 121.
But the determination of when a legal-malpractice action accrues for purposes of the statute of limitations does not depend on a subjective interpretation of when plaintiff "ended" or "terminated" the attorney-client relationship. Rather, MCL 600.5838(1) requires that an analysis of accrual focus on the date that the defendant attorney discontinued serving the plaintiff in a professional capacity, "regardless of the time the plaintiff" had knowledge of the claim. In Gebhardt v. O'Rourke, 444 Mich. 535, 510 N.W.2d 900 (1994), our Supreme Court examined the application of MCL 600.5838 in a legal-malpractice case. The Supreme Court observed that the "statute is unambiguous" and held that a "client has up to two years from the time his attorney stops representing him regarding the matter in question to bring a malpractice suit." Id. at 541, 544, 510 N.W.2d 900. Rinaldo did not and could not stop representing plaintiff until (1) he fired her, (2) the USPTO received and accepted plaintiff's request to revoke Rinaldo's power of attorney, or (3) she communicated to plaintiff that she had *126 terminated their relationship. None of these events occurred until October 2005.
Citing Kloian v. Schwartz, 272 Mich. App. 232, 237, 725 N.W.2d 671 (2006), the majority holds that plaintiff's "retention of an alternate attorney effectively terminate[d] the attorney-client relationship." Ante at 119. In my view, this is a patently incorrect conclusion because the alternate attorney plaintiff retained, Weintraub, worked with Rinaldo and not in her stead. Rinaldo, Weintraub, and plaintiff met together on November 7, 2003, and Rinaldo subsequently prepared a "Memorandum of Understanding" regarding that meeting that reflected her intent and designated assignment within plaintiff's legal team to "draft and file an amendment consistent with the claims presented at the meeting by Weintraub." Despite plaintiff's retention of Weintraub, Rinaldo clearly continued to serve as plaintiff's official patent counsel.
Furthermore, the statement from Kloian on which the majority relies in my view qualifies as dictum, unnecessary to that decision and simply incorrect under the plain language of MCL 600.5838. In Kloian, the defendant attorneys informed the plaintiff in writing that the trial court had dismissed the plaintiff's case. In the same writing, the defendant attorneys additionally informed the plaintiff that they would not prosecute an appeal on the plaintiff's behalf. Id. at 236, 725 N.W.2d 671. This Court held that
in the absence of an attorney's dismissal by the court or the client, and in the event that an attorney sends notice of withdrawal as his or her final act of professional service, a legal malpractice claim with respect to a particular matter that has been finally dismissed by order of the trial court accrues at the time affirmative notification of withdrawal is sent. [Id. at 238, 725 N.W.2d 671.]
Unlike the defendant attorneys in Kloian, Rinaldo did not send plaintiff a "notice of withdrawal" as his patent counsel. The October 2005 transmission to Rinaldo of plaintiff's revocation of her power of attorney constituted the only "affirmative notification" that Rinaldo no longer represented plaintiff before the USPTO. In my view, Kloian supports a conclusion that plaintiff's legal-malpractice claim did not accrue until October 2005, when Rinaldo received the affirmative notification that plaintiff had terminated their attorney-client relationship.
Elsewhere in Kloian, this Court observed that "an attorney's representation of a client generally continues until the attorney is relieved of that obligation by the client or the court." Id. at 237, 725 N.W.2d 671. This Court followed that sentence with a statement that now serves as the linchpin of the majority opinion: "`Retention of an alternate attorney effectively terminates the attorney-client relationship.'" Id., quoting Mitchell v. Dougherty, 249 Mich.App. 668, 683, 644 N.W.2d 391 (2002). The Kloian opinion identified Maddox v. Burlingame, 205 Mich.App. 446, 450, 517 N.W.2d 816 (1994), as the original source of the language "retention of an alternate attorney."
In Maddox, however, this Court noted that the retention of alternate counsel did not terminate the attorney-client relationship or alter the date on which the plaintiff's legal-malpractice claim accrued:
Although plaintiffs already had consulted alternative counsel in Florida in August 1988, we do not believe that this necessarily terminated the attorney-client relationship between the instant parties because defendant earlier had directed plaintiffs to consult with Florida counsel in order to protect fully plaintiffs' interests under Florida law. In other words, plaintiffs' Florida counsel *127 was not consulted in place of, but in addition to, defendant. [Id. at 451, 517 N.W.2d 816.]
In my view, the relationship between Weintraub, Rinaldo, and plaintiff was directly analogous to that of the lawyers and parties involved in Maddox. Weintraub and plaintiff deliberately continued Rinaldo as plaintiff's official patent counsel and relied on her efforts in this role to correct the patent. They planned to delay her discharge until Weintraub officially substituted as plaintiff's counsel.
The majority clearly believes that plaintiff, Nedelman, and Weintraub conducted themselves in an offensive manner. That may be an accurate perception. Regardless of the negative and derogatory behind-the-scenes discussions between plaintiff, Nedelman, and Weintraub regarding Rinaldo, plaintiff intended that she remain his official patent counsel until Weintraub officially superseded her. Further, the character of a client's conduct is not an element of the definition of accrual under MCL 600.5838.
In my view, the majority has essentially rewritten the text of that statute in order to punish plaintiff for his duplicity regarding Rinaldo. From a pure policy perspective, it may be appropriate to penalize clients who behave as plaintiff did and to prohibit "strategic concealment" of an intent to discharge counsel. But the statute simply cannot be read to provide that a legal-malpractice claim accrues when a client decides to fire his or her lawyer or discusses with alternate counsel a plan to replace the current lawyer. Rather, the statute clearly and unambiguously provides that a malpractice claim accrues "at the time [the defendant] discontinues serving the plaintiff in a professional ... capacity as to the matters out of which the claim for malpractice arose, regardless of the time the plaintiff discovers or otherwise has knowledge of the claim." MCL 600.5838(1) (emphasis supplied). According to the USPTO, Rinaldo continued to represent plaintiff and remained his official patent counsel until October 20, 2005. In the absence of any communications to the contrary, Rinaldo remained responsible for the prosecution of the May 2003 patent reissue application, at least until she learned in October 2005 that plaintiff had revoked her power to act as his patent counsel.
Because plaintiff filed this lawsuit in February 2006, I conclude that it was timely filed and would reverse the trial court's grant of summary disposition.
NOTES
[1]  Rinaldo worked for Kohn & Associates, P.L.L.C., at the time this claim arose, and Wright sued both Rinaldo and the law firm for Rinaldo's alleged malpractice. However, for ease of reference, and because Rinaldo's conduct is at issue, we refer to Rinaldo alone for the remainder of this opinion.
[2]  After he received the letter, Wright wrote to Nedelman and Weintraub and stated:

What response (if any) should I make to Amy regarding the letter she sent to me. She will get suspicious if I do not respond.
[3]  Pursuant to MCR 2.116(C)(7), the trial court granted summary disposition to defendants because Wright's claim was barred by the statute of limitations. As this Court explained in Citizens Ins. Co. v. Scholz, 268 Mich.App. 659, 662, 709 N.W.2d 164 (2005):

This Court reviews de novo a trial court's grant of summary disposition under MCR 2.116(C)(7). Maiden v. Rozwood, 461 Mich. 109, 118, 597 N.W.2d 817 (1999). Summary disposition is properly granted under MCR 2.116(C)(7) when an action is time-barred. Id. at 118 n. 3, 597 N.W.2d 817. Young v. Sellers, 254 Mich.App. 447, 449, 657 N.W.2d 555 (2002). "`[A]bsent disputed questions of fact, whether a cause of action is barred by a statute of limitations is a question of law that this Court also reviews de novo.'" Id. at 450, 657 N.W.2d 555 (citation omitted).

[5]  We agree with Rinaldo that the trial court simply made a clerical error when, at the end of its opinion and order, it stated that "clearly Rinaldo's representation of [Wright] ended when he filed a revocation of the power of attorney on December 18, 2003, more than two years before the date the instant Complaint was filed." (Emphasis added.) As is clear from the rest of the trial court's opinion, the court believed that the attorney-client relationship ended when Wright executed the documents that revoked Rinaldo's power of attorney and granted it to Weintraub, not when Weintraub filed the documents with the patent office.
[6]  We note that Wright has changed his position with regard to the accrual date. In the trial court, Wright argued that the revocation of Rinaldo's power of attorney was not effective until the patent office officially accepted it in October 2005. Now he argues that the revocation did not occur until Weintraub mailed the revocation to the patent office on February 23, 2004. However, the evidence shows that Wright replaced Rinaldo with other counsel, Weintraub, well before the patent office was informed of the change.
