ORDER
PER CURIAM.
A combined petition for panel rehearing and rehearing en banc was filed by Plaintiff-Appellant, Avid Identification Systems, Inc. ("Avid"). Separately, Avid filed a motion to join in the pending en banc review in Therasense v. Becton Dickinson and Co., XXXX-XXXX, XXXX-XXXX, XXXX-XXXX, XXXX-XXXX, XXXX-XXXX or, alternatively, to stay the mandate of this case pending disposition of Therasense. The panel denied Avid's motion. The combined petition and motion were referred to the circuit judges who are in regular active service. A poll was requested, taken, and failed.
Upon consideration thereof,
IT IS ORDERED THAT:
(1) The motion to join in the pending en banc review in Therasense v. Becton Dickinson and Co., XXXX-XXXX, XXXX-XXXX, XXXX-XXXX, XXXX-XXXX, XXXX-XXXX or, alternatively, to stay the mandate of this case is denied.
(1) The petition for panel rehearing is denied.
(2) The petition for rehearing en banc is denied.
(3) The mandate of the court will issue on July 23, 2010.
NEWMAN, Circuit Judge, dissents from the denial of the request for a stay.
NEWMAN, Circuit Judge, dissenting from denial of the request for a stay.
Avid moves this court to stay its petition for rehearing en banc until our en banc consideration of Therasense, Inc. v. Becton, Dickinson & Co., 593 F.3d 1289 (Fed. Cir.2010), which bears on the precise issue of Avid's appeal, that is, the criteria for "inequitable conduct" during patent prosecution. I would grant this stay. The law as applied in Avid is subject to conflicting precedent, a conflict whose resolution is reasonably likely to alter the result. Thus it is prudent, and just, to hold Avid's petition while the law is clarified.
The court today has declined to do so, rendering the subject patent permanently unenforceable, although the patent was found valid on the same prior art that is the basis for its unenforceability.
The practice of staying the finality of related cases while the law is clarified is not unusual. The Supreme Court often holds petitions for writ of certiorari in cases involving the same issue being decided in another case before the Court. As explained in Lawrence v. Chater, "`We fulfill our judicial responsibility by instructing the lower courts to apply the new rule retroactively to cases not yet final.'" 516 U.S. 163, 167, 116 S.Ct. 604, 133 L.Ed.2d 545 (1996) (quoting Griffith v. Kentucky, 479 U.S. 314, 323, 107 S.Ct. 708, 93 L.Ed.2d 649 (1987)). Thus the Supreme Court "regularly hold[s] cases that involve the same issue as a case on which certiorari has been granted and plenary review is being conducted in order that (if appropriate) they may be [granted, vacated and remanded] when the case is decided." Id. at 181, 116 S.Ct. 604 (Scalia, J., dissenting on other grounds). The Court elaborated that this practice conserves judicial resources while alleviating the potential for unequal treatment of pending cases raising similar issues. Id. at 167, 116 S.Ct. 604.
Such consideration is equally salutary upon en banc review in this court, when the purpose of the review is to establish consistent national law, and other pending cases are reasonably likely to be affected. As applied to Avid, it is grievously unjust to eradicate this patent on grounds that may soon be changed by the en banc court. Our Order in Therasense is of broad *1332 range, in the context of "inequitable conduct" in patent prosecution, and includes the following questions concerning materiality:
Q3. What is the proper standard for materiality? What role should the United States Patent and Trademark Office's rules play in defining materiality? Should a finding of materiality require that but for the alleged misconduct, one or more claims would not have issued?
Therasense, Inc. v. Becton, Dickinson & Co., Nos.2008-1511, 2008-1512, 2008-1513, 2008-1514, 2008-1595, 2010 WL 1655391, at *1 (Fed.Cir. April 26, 2010) ("Order"). Extensive amicus curiae participation has ensued, for the burden on the innovation community of this court's inconsistent rulings has achieved national notoriety. See, e.g., 155 CONG. REC. S2715 (daily ed. Mar. 3, 2009) (statement of Sen. Hatch) ("The inequitable conduct defense is frequently pled, rarely proven and always drives up the cost of litigation tremendously.").
This court held that Dr. Stoddard's demonstration during the Livestock Committee trade show of what the panel calls "some of Avid's technology," and Avid calls a "precursor product," was material to patentability and that Dr. Stoddard was required to assure that the patent examiner was informed.[1] According to the panel opinion, the district court "found that the precursor product, while not invalidating, reflected the closest prior art, and thus was highly material to patentability." Avid Identification Sys., Inc. v. Crystal Import Corp., 603 F.3d 967, 973 (Fed.Cir. 2010) ("Avid II"). While "closest prior art" has been discussed in the context of whether certain information is cumulative of that already presented to an examiner, see, e.g., Astrazeneca Pharms. LP v. Teva Pharms. USA, 583 F.3d 766, 773-75 (Fed. Cir.2009), it has never been the law that information is "highly material" simply because it is "closest." It is not disputed that whatever was demonstrated was not an invalidating disclosure of the patented invention, and not a sale or offer to sell the patented invention, for the jury found that the demonstration at the Livestock Committee was not invalidating. See Avid I, 2007 WL 2901415, at *1.
Dr. Stoddard, who is the president of Avid, is a veterinarian whose principal occupation is running an animal hospital; he is not an electronics engineer and not a chip designer and not an inventor of the patented device and not a lawyer. See Avid II, 603 F.3d at 970. On the undisputed fact that the challenged information is not invalidating, the court's holding of inequitable conduct is sufficiently questionable to warrant a stay until this court resolves the larger issues before us, including the en banc Order's query: "Should a finding of materiality require that but for the alleged misconduct, one or more claims would not have issued?" Order, 2010 WL 1655391, at *1. It is at least possible that the court will answer this question in the affirmative. Although I do not venture to guess how Therasense will fare overall, it is not unreasonable to expect that it may affect the Avid decision.
The Avid panel applied the former Rule 56 standard of materiality as stated in J.P. Stevens & Co. v. Lex Tex Ltd., 747 F.2d *1333 1553, 1559 (Fed.Cir.1984), although this standard was abandoned by the PTO in 1992. The information here criticized does not appear to violate the current Rule 56 standard, and Dr. Stoddard is not within the cadre upon whom is placed the obligation of understanding the patent law, as Judge Linn explained in his dissent. I must, respectfully, dissent from the court's refusal to stay this appeal in view of the en banc proceeding in Therasense.
