CAFC Forced to Disturb Earlier Ruling Based on More Liberal Patent Reexamination Standards

Patent reexamination is often initiated in parallel with an ongoing infringement litigation. In some cases, an infringer that fails to prove invalidity in the courts can effectively “undo” the effect of the earlier court judgement via an ex parte patent reexamination (EXP) filing.

Back in December, the CAFC considered this “do over” tactic in the case of In re Construction Equipment. Last week, the very same procedural fact pattern presented itself to the CAFC. Once again, Judge Newman decried the potential undermining of previously settled court rulings via ex parte patent reexamination.

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.

BPAI Reverses Rejections on CAFC Claim Construction

The seemingly never ending saga of the NTP patent reexaminations took yet another interesting turn yesterday. The BPAI issued revised decisions on remand that reversed the earlier rejections of some of the NTP claims. As a reminder, the reexamination of the NTP patents began during the litigation between NTP v. RIM.  The reexaminations continued at the USPTO in parallel with the then ongoing, and now infamous, litigation.  However, the co-pending litigation continued on to the settlement, narrowly avoiding a disruption of RIM’s business in the U.S via court imposed injunction.

Now, some 6+ years later, the reexaminations may be close to a conclusion (absent further appeal by NTP).

The revised decisions stem from the CAFC remand on claim construction issues relating to the definitions of “electronic mail” or “electronic mail message.” As a result of the revised construction, NTP has manged to claw back some of their previously rejected claims.

New Appeal Rules Effective January 23, 2012

This past Monday the USPTO released the final rule package pertaining to the Rules of Practice Before the Board of Patent Appeals & Interferences in Ex Parte Appeals. (here).

This final rule notification stems from the earlier notice of proposed rule making issued last November. The rules are limited to ex parte proceedings only and have no bearing on patent interferences, or inter partes patent reexamination. Likewise, the new rules will not control Inter Partes Review or Post Grant Review. The final rules become effective on January 23, 2012. (for appeals initiated on or after the effective date)

In response to the original publication of the rules, I pointed out that the proposal provides an interesting safeguard against new rejections in an Examiner Answer. Namely, the filing of a 1.181 petition challenging such a rejection tolls the period for filing a Reply brief. Thus an Applicant may await decision on the petition before filing the Reply. This provision will be very helpful in patent application prosecution, but may aggravate ex parte reexamination pendency if abused.

USPTO Proposal Forces Patentee Cooperation in Violation of Statute?

Last Monday, I proposed managing petition practice in inter partes patent reexamination based on the patent interference model already in place. As a reminder, this proposal is responsive to the proposed collection of working concepts and initiatives published in the Federal Register for the purpose of streamlining patent reexamination. (a copy of the Federal Register Notice is found here) I discussed this proposal at the USPTO, along with other speakers on June 1, 2011. (webcast and other materials here)

As I mentioned in last week’s post, the USPTO proposal to modify and make permanent the Pilot Program for Waiving the Patent Owner Statement was not discussed in detail during the meeting. However, this proposal, at least from feedback I have received, is one of the more controversial.

In a nutshell, the USPTO is proposing to modify the existing Pilot Program by: (1) Making the Pilot Program permanent; and (2) Issuing a first “provisional” first action together with the Order of reexamination for those Patentees that do not agree to waiver. With respect to the “provisional” first action, unless a Patentee files a Statement overcoming the rejections in the Provisional Action, the next action would issued as a Final Rejection; therein lies the controversy.

starStar Scientific’s Belated Victory in Patent Reexamination, Missed Opportunity?

Last week, Star Scientific’s ex parte patent reexaminations (90/009,372 & 90/009,375) were favorably terminated based upon responses filed in November of 2009.  The reexaminations are directed to Star’s patented tobacco curing technologies that are the subject of an ongoing litigation with R.J Reynolds.

The 16 month delay between the November 2009 filing and March 2011 termination was the result of a procedural dispute. I discussed this development last Spring for the purposes of illustrating the importance of filing a proper interview summary in ex parte patent reexamination. As I pointed out at that time, misguided petition practice can turn a relatively minor miscue into a much larger problem.

In June of of 2009, a Maryland jury determined that Star’s patents were invalid. The jury also found that RJR did not infringe either patent. Star appealed to the Court of Appeals for the Federal Circuit (CAFC), oral arguments were heard on January 11, 2011. In their appeal, Star is seeking a new trial, alleging that RJR tainted the jury by referencing improper evidence.

On Friday, Star issued a press release touting their patent reexamination results. But, with the CAFC appeal briefed and argued, does the reexamination have any relevance at all?

Request Ex Parte Patent Reexamination, Lose, RepeatFor Patent Owners, one of the more frustrating aspects of ex parte patent reexamination is that the experience can be never ending. That is to say, even when an ex parte patent reexamination is favorably concluded, the same challenger can simply refile a second request to take another shot at the patent. Of course, the second request must present new, non-cumulative questions of patentability. Still, as the SNQ standard is a relatively low bar, seriatim filings are fairly commonplace. (In inter partes patent reexamination, estoppel provisions effectively prevent this tactic).Practically speaking, in the case of a parallel litigation, seriatim requests are not viewed favorably by courts. After all, you can’t simply present new invalidity contentions in court should the first set fail.Recently, in Voda v. Medtronic Inc., et. al. (OKWD) (here) the defendants were able to secure a stay pending a first request for patent reexamination. Shortly thereafter, the reexamination concluded favorably to the Patent Holder and the stay was lifted. Next, the defendants filed a second request for ex parte patent reexamination, and then a third request along with a second motion to stay the case. The court denied the second motion to stay, explaining: The court finds the first factor weighs against granting a stay. The first reexamination request resulted in a fourteen-month delay, and notice of the USPTO’s decision on that request was further delayed by defendants’ filing a second ex parte request for reexamination. Moreover, defendants’ filing of the third reexamination request and concomitant request for a stay has already resulted in additional delay as the court had to reschedule the status conference set for January 2011. Simplification of the issues to be tried in this action is likely to occur only if the USPTO issues a decision rejecting the patent’s claims. Given the recent confirmation of the ‘213 patent, that outcome is not certain and therefore this factor does not weigh in favor of granting a stay. Finally, defendants’ argument that this matter is in its early stages ignores the fact that the case has been pending for two years. This factor, therefore, also weighs in favor of denying defendants’ second motion to stay. (emphasis added)USPTO statistics indicate that inter partes patent reexaminations are far more effective for Requesters (i.e., claims amended and/or cancelled). Of course, such proceedings are not available for all patents, as was the case in Voda.The greater success rate of inter partes patent reexamination is often attributed to Requester participation; yet, this only be  part of the story. Due to the estoppel provisions of inter partes patent reexamination, the number of SNQs presented relative to ex parte patent reexamination tend to be higher. In other words, there is no “holding back” of art as is often the case with initial ex parte filings. Additionally, inter partes requests tend to be of a much higher quality due to the estoppel risk involved.For those Requesters seeking to employ an ex parte patent reexamination for stay purposes, the first shot might need to be your best shot.This case was brought to my attention by the great Docket Navigator.

For Patent Owners, one of the more frustrating aspects of ex parte patent reexamination is that the experience can be never ending. That is to say, even when an ex parte patent reexamination is favorably concluded, the same challenger can simply refile a second request to take another shot at the patent. Of course, the second request must present new, non-cumulative questions of patentability. Still, as the SNQ standard is a relatively low bar, seriatim filings are fairly commonplace. (In inter partes patent reexamination, estoppel provisions effectively prevent this tactic).

Practically speaking, in the case of a parallel litigation, seriatim requests are not viewed favorably by courts. After all, you can’t simply present new invalidity contentions in court should the first set fail.

Patentees Frustrate USPTO Efforts to Reduce Ex Parte Reexamination Pendency

 chart1(click to enlarge)

As discussed in previous posts, in August of 2010 the USPTO announced a pilot program, aimed at reducing the pendency of ex parte patent reexamination by 3-5 months. The program entitled “Pilot Program for Waiver of Patent Owner’s Statement in Ex Parte Reexamination Proceedings” is triggered once a new ex parte reexamination request is accorded an initial filing date.

In formulating the program, the USPTO noted that roughly 10% of Patentees file such statements. Thus, by presenting the option to waive the statement, arguably, 90% of filings could be accelerated by 3-5 months. Yet, initial response to the program seemed to indicate that Patentees favored this de facto delay.

Now that a larger number of proceedings have been subject to the program a clearer picture is emerging.Continue Reading Patent Reexamination Pilot Program Update

Dispute with USPTO Ripens for District Court?

As some may recall, in 2009 patent owner Sigram Schindler pursued a declaratory judgment action against the USPTO in the Eastern District of Virginia. (EDVA). The DJ action questioned the propriety of foreclosing district court review of USPTO action in the ex parte patent reexamination of Sigram’s U.S. Patent 6,954,453.

More specifically, the DJ action (previous discussion here) sought a determination as to whether the USPTO’s interpretation of 35 U.S.C. § 306, was proper.  The USPTO interprets 35 U.S.C. § 306 as prohibiting a Patentee in an ex parte patent reexamination from obtaining judicial review of a decision of the Board of Patent Appeals & Interferences (BPAI) by filing a civil suit against the USPTO in federal district court.

Rather than deciding the issue, the EDVA simply noted that the question was not yet ripe due to the absence of a BPAI decision. Yesterday, a decision issued (here) in the reexamination (90/010,017) affirming the examiners rejection of the reexamined claims. Seems like matters have ripened…..

USPTO Relies on Case Law Predating Interrogatory Power of 37 CFR 1.105

As discussed previously, it is not uncommon for Patentees to introduce evidence of secondary indicia of non-obviousness when faced with an obviousness rejection. To be considered persuasive, the examiner must be able to identify a nexus between the merits of the claimed invention and the evidence of secondary considerations. The term “nexus” identifies a factually and legally sufficient connection between the objective evidence of nonobviousness and the claimed invention so that the evidence is of probative value in the determination of nonobviousness. In the vast majority of cases involving such evidence, the required nexus is deemed insufficient.

Yesterday, a typical rejection of such evidence was once again demonstrated by the BPAI in Ex Parte Smiths Interconnect Microwave Components. Inc. Interestingly, the Patentee argued that a nexus was demonstrated as the sales figures provided related to the product described in their patent. In rejecting this nexus, the BPAI relied on Ex parte Remark, 15 USPQ2d 1498, 1502-03 (BPAI 1990). The Board explained the holding of Remark as clarifying that [i]n civil litigation, once a prima facie nexus is demonstrated the burden switches to the opposing party to show that commercial success was due to extraneous reasons, while in ex parte proceedings the USPTO lacks the evidentiary means to show that commercial success is due to reasons other than the merits of the claimed invention.

Yet, the above noted case predates the enactment of 37 CFR § 1.105. Rule 105 provides the very evidentiary means to explore deficiencies in submitted declarations.
