Willfullness Determination Opens Door to Prejudice

One purpose for introducing evidence of an ongoing patent reexamination in a parallel litigation is to avoid a post filing (i.e., complaint) willfulness determination. The existence of an ongoing patent reexamination may be admitted to demonstrate that the accused infringer was not objectively reckless in its actions irrespective of its prior knowledge of the asserted patent.

Some courts have found that reexamination evidence defeats a finding of willfulness, these courts typically examine the status of the claims in the reexamination proceeding at the time of the willfulness determination, finding that the weight of the reexamination evidence depends on whether the reexamination proceedings are complete and whether the patent claims have undergone substantive changes in reexamination. When seeking introduction of such evidence, depending upon the court, the stage of the parallel litigation (Summary Judgment, JMOL, Pre-Trial Motions) may determine whether or not it is admissible.

In recent years, courts have been reluctant to admit evidence of an ongoing patent reexamiantion at trial. This is because the presumption of validity may be undermined by communicating to the factfinder(s) that the USPTO has changed their mind. This trend is especially prominent in plantiff forums such as Texas.  Read the rest of this entry »

Parallel Litigation Settles, Now What?

With the vast majority of patent reexaminations now being conducted concurrent to a district court or ITC proceeding, a common question of Patentees is “what becomes of the patent reexamination once the litigation settles?”

In the case of ex parte patent reexamination, the answer is simple: the reexamination continues unaffected. Indeed, as demonstrated a few weeks back (In Re Construction Equipment, CAFC (2011)), the ultimate outcome of the ex parte reexamination can even effectively reverse an earlier decision of the CAFC.

On the other hand, if the pending reexamination is an inter partes patent reexamination (IPX), the answer will depend on the nature of the terms of the settlement agreement. In a best case scenario for Patentee, the IPX proceeding may be vacated altogether by operation of estoppel. Of course, to trigger IPX estoppel, the settling defendant/requester must agree to a consent consent judgement in the district court (not effective in the ITC as estoppel does not apply) that they failed to prove invalidity. In most cases, defendants are loathe to publicly admit defeat. Still, unwary Patentes may be walking away from significant opportunity if just swinging for the fences. Read the rest of this entry »

Determination of Non-Obviousness by USPTO Disregarded by Court

Last week’s CAFC decision in In re Construction Equipment decided the validity of U.S. Patent 5,234,564…..again. In the first appeal, decided in 2001, the CAFC upheld the validity determination of the District Court. In the second appeal, decided last week, the CAFC considered an appeal from the USPTO rejecting the claims of the ‘564 patent in ex parte patent reexamination. In their second decision, the CAFC found the ‘564 Patent invalid in light of some of the very same prior art references at issue in the first appeal.

In her dissent Judge Newman questioned the constitutionality of the USPTO looking over the shoulder of the CAFC.

In a case of “turnabout is fair play,” last Friday, a United States District Judge for the District of Connecticut considered, and disregarded, the USPTO’s reexamination analysis of the same prior art in Jacobs Vehicle Equipment Co. v. Pacific Diesel Brake Co. et al. (D.Conn). Read the rest of this entry »

CAFC Appeal Result Undone 11 Years Later

Patent reexamination is often initiated in parallel with an ongoing infringement litigation. In the case of a parallel inter partes proceeding (IPX), the first of the proceedings to conclude (litigation or IPX) controls the outcome of the other by operation of statutory estoppel. As such, a final holding in the parallel court proceeding will end an ongoing IPX. Moreover, the losing party would be precluded from seeking IPX at a later date.

On the other hand, ex parte patent reexamination (EXP) has no such statutory “shut off valve.” Thus, even a party that was bound by IPX estoppel could file a request for ex parte patent reexamination. In this way, the infringer could attempt to “undo” the effect of the earlier, final, court judgement by invalidating the patent via the EXP filing.

As I explained this past August, the CAFC questioned this “do-over” practice during the oral argument of In re Construction Equipment. Last week the CAFC issued a decision in this case. In the process, the CAFC disturbed the holding of their first decision, issued some 10 years earlier. Read the rest of this entry »

Parallel Patent Reexamination Qualifies as Newly Discovered Evidence Under Fed. R. Civ. P. 60(b)

It is well established that the USPTO utilizes different standards of evidence and claim interpretation in patent reexamination. Likewise, there is no presumption of validity in patent reexamination. For this reason, district court/ITC claim construction findings (i.e., Markman Orders) are not binding on the USPTO. In re Trans Texas Holdings Corp., 498 F.3d 1290 (Fed. Cir. 2007). Yet, the findings of the USPTO with regard to claim construction can have significant impact on the court rulings.

For example, this past January, in St. Clair Intellectual Property Consultants, Inc. v. Canon Inc., (Fed. Cir. 2011, non-precedential), the CAFC reversed a lower court claim construction ruling, based in part, on the findings of USPTO examiners in patent reexamination, Read the rest of this entry »

CAFC Revisits “Loser Estoppel” in Patent Reexamination

While reexamination is often initiated parallel to litigation, some have relied upon reexamination in post-trial settings to get out from under injunctions and/or jury verdicts.

One of the more well known cases in this regard is In re Trans Texas Holdings Corp., 498 F.3d 1290 (Fed. Cir. 2007). In Trans Texas, the patent being reexamined was subject to an infringement suit, in which the district court had issued its claim construction ruling (in a district court opinion) as to the definition of a term. The parties ultimately reached a settlement before trial, and the district court issued an “Order of Dismissal with Prejudice.” The patent owner relied on that district court claim construction ruling in a reexamination proceeding, and argued that the Office was bound by that district court claim construction ruling, under the doctrine of issue preclusion. The Federal Circuit stated that issue preclusion could not be applied against the Office based on a district court holding in an infringement proceeding, since the Office was not a party to that earlier infringement proceeding. See Also In re Translogic Tech. Inc. (CAFC 2007)

Yesterday, the CAFC heard oral argument in the case of In re Construction Equipment. Construction appealed from a decision of the BPAI in ex parte patent reexamination that found the claims of the patent anticipated and/or obvious. Previously, the CAFC found the Construction patent not invalid on appeal from the District Court. Thereafter, the appellant pursued ex parte reexamination on some of the very same art previously considered.

During oral argument the court, sua sponte, questioned the propriety of the USPTO’s seeming dismissal of the Court’s previous validity ruling. Read the rest of this entry »

Callaway Pro V1 Golf Dispute Taken to Virginia District Court

This past January, I recounted the longstanding dispute between Callaway Golf and Acushnet. Acushnet is the parent company of Titleist, maker of the ProV1 family of golf balls. Callaway has asserted that the ProV1 balls infringe several of their patents (6,210,293, 6,503,156, 6,506,130, 6,595,873) in the Delaware District Court.

In 2006, Acushnet sought inter partes patent reexamination of the Callaway patents. In March of this year the BPAI decided the appeals of these reexaminations, finding the asserted claims of the Callaway patents invalid. Likewise, the same claims were found invalid in March of 2010 by the Court (neither dispute has made it to the CAFC).

Interestingly, patent reexamination was sought by Acushnet despite a 1996 contractual agreement between the companies that mandated all proceedings be conducted in the Delaware court. In fact, the Court has found Acushnet to have breached the terms of the settlement agreement by virtue of the patent reexamination filings (decision here).

At the outset of the reexamination proceedings Callaway attempted to have the reexamination proceedings vacated Read the rest of this entry »

Early Stage Reexamination Result Lacks Probative Value for Summary Judgment Purposes

As discussed last month, evidence of a concurrent reexamination proceeding is typically excluded in district courts as lacking relevance under FRE 402 and/or as being more prejudicial than probative under FRE 403, when offered for purposes of demonstrating invalidity.

As explained last week in Volterra Semiconductor Corporation v. Primarion, Inc., et. al. (NDCA):

With respect to the PTO Initial Office Actions and reexamination orders, it is well established that while statements made by the patentee during reexamination proceedings may be probative as to questions of claim construction, see E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1439 (Fed. Cir. 1998), preliminary decisions and actions by the PTO in the course of a reexamination proceeding are not probative of invalidity. . . . Defendants have relied on the preliminary opinions expressed by the PTO on questions of invalidity. As these opinions are only preliminary, however, they have no probative value on that question . . . Therefore, Plaintiff’s objections to Defendants’ reliance on the PTO office actions and orders are sustained to the extent that Defendants rely on them to support their positions regarding invalidity.

For the above reasons, parallel patent reexamination filings are almost never concurrently filed for the purpose of convincing a fact finder that a patent should be found invalid. Instead, the benefits of parallel patent reexamination have been discussed at great length here as potentially impacting other aspects of litigation, “Is Evidence of Parallel Reexamination Proceedings Admissible at Trial?” (Parts I, II, III, and IV). In past posts, the benefits of parallel patent reexamination evidence are explained as: aiding an inequitable conduct defense, impacting claim construction,  rebutting allegations of willful infringement, obtaining patent owner admissions to support a non-infringement defense, obtaining an intervening rights defense, providing grounds to stay a district court proceeding, and supporting/opposing injunctive relief.

In the above case, although inequitable conduct was denied on summary judgement for intent reasons, the materiality determination of the reexamination with respect to common references was considered by the court.

This case was brought to my attention by the great Docket Navigator.

Using a Parallel Patent Reexamination as Evidence of Invalidity?

Increasingly, courts are presented with evidence of a parallel patent reexamination and must determine whether/when such evidence is admissible.

Admissibility of evidence is governed by the Federal Rules of Evidence (“FRE”).  In recent cases, where the admissibility of evidence of concurrent reexamination proceedings has been offered with respect to the ultimate question of validity, patentees have attempted to use three rules of evidence to exclude such evidence, FRE 402, FRE 403, and FRE 802.

FRE 402 excludes irrelevant evidence.  Patentees, hoping to keep evidence of concurrent reexamination proceedings out of the litigation and away from the jury, have argued that this evidence is irrelevant and should be excluded under FRE 402.  Several courts have agreed.  Read the rest of this entry »

Additional Prosecution History Proves Crucial

A successful reexamination from a defendant perspective does not always result in an overt claim change or cancellation. In other words, even where claims are confirmed, statements in the reexamination record that are inconsistent with arguments made in a concurrent litigation, or that rise to the level of an outright disclaimer, may provide new, non-infringement positions to defendants.

This week, the CAFC relied upon statements made by a Patentee in the patent reexamination of U.S. Patent 5,355,964 to affirm claim construction findings of the EDVA and NDCA. Read the rest of this entry »
