Are Two Heads Better than One?

When faced with parallel PTAB and District Court/ITC proceedings, both patent owners and petitioners alike must decide whether to use the same expert in each proceeding, or hire a dedicated expert for each. Certainly there is much efficiency to be gained using the same person — not to mention the seeming likelihood of greater consistency in opinion.

But it is preferable, in my view, to use separate experts. This often limits document inventory for the PTAB deposition, and opposing counsel is less inclined to extend the deposition with questions that are designed to illicit fodder for the litigation effort. Likewise, use of separate experts does not give litigation counsel extra “shots” at the same witness.  Also, with the PTAB now applying the same Philips claim construction of the district court, as discussed previously, there is also an increased interest in claim construction related testimony should the PTAB proceeding fail.

Recently, the District of Delaware considered whether a litigation expert should have to divulge any consulting (non-testifying) work with respect to an earlier PTAB proceeding.

Previous Testimony May Highlight Infringement

When a failed PTAB petitioner heads back to court, Patent Owners sometimes seek to leverage the broad claim reads proposed at the PTAB to demonstrate infringement. Recently, in ChanBond, LLC v. Atlantic Broadband Group, LLC, et al., (D.DE., Apr. 19, 2021), the district court considered the admissibility of previous IPR testimony to an infringement case.

Frequent Losing Argument at the PTAB Finds Rare Exception

A common losing argument at the PTAB is that a reference used in an obviousness combination is non-enabling.  The reason this argument fails is that a reference is prior art for all that it teaches.  But even this proposition has its exceptions.  For example, one would not expect a Dick Tracy comic from the 1930s showing a communicating wristwatch to somehow preclude patents on today’s smartwatches.

But where is the line drawn as to aspirational disclosures and, fair, prior art teachings?

Final Rule Package Updates Current PTAB Practices with Two Additions

The USPTO will publish a final rule package today (draft here) that largely presents the earlier Notice of Proposed Rule Making in final form. Most of the changes addressed rules outdated by the SCOTUS decision in SAS Institute, or simply codified existing practices, such as sur-replies.  As such, the bulk of the earlier proposals were not controversial.

However, the earlier Notice also proposed one new idea, eliminating the presumption accorded to petitioner testimonial evidence in the preliminary proceeding (when disputed by patent owner testimonial evidence to the contrary). This proposal was the focus of much of the public commentary.

Despite most bar associations opposing this change, the final rule will in fact eliminate the presumption, starting January 11th (January 9th being a Saturday). The Final Rule also adds a new rule-based prohibition on Sur-reply filings.

CAFC Faults PTAB Nexus Presumption

A proper obviousness analysis under Graham v. John Deere analyzes four factors: (1) the scope and content of the prior art; (2) the differences between the prior art and the patent claims; (3) the level of ordinary skill in the art; and (4) secondary considerations or “objective indicia” of non-obviousness. Yet, objective indicia arguments are relatively uncommon in the predictable arts.  And even when they are advanced, the argument is rarely effective. This is because establishing  a nexus between a patent claim and such amorphous concepts as “commercial success” (the most commonly advanced form of indicia) is a far more complex undertaking than most practitioners appreciate.

A patentee is entitled to a rebuttable presumption of nexus between its asserted objective indicia and a patent claim if the patentee shows that the indicia is tied to a specific product and that the product is the invention disclosed and claimed.  Earlier this week, the Federal Circuit analyzed how close a claim needs to be to the purported “invention” to qualify for the presumption of nexus.

POPR Disclaimer Dooms Infringement

Some weeks back I explained the varied uses of Patent Trial & Appeal Board (PTAB) trial evidence in district court trial records. However, it is not necessary for a trial to occur for patent challengers to create litigation value. For example, often times a petition will apply prior art that operates in a similar fashion to the accused product.  In distinguishing that art, the Patent Owner is effectively arguing against infringement.

In such cases, a failed AIA trial petition (art distinguished) can result in ultimate victory on the ligation side.

Continuous Diligence Not Required

Although the United States has been a first-inventor-to-file patent system since March 16th 2013, the patents of the previous first-to-invent system will linger for many years to come. For those patents, the ability to “swear behind” prior art will remain.

Under pre-AIA §102(g), when two persons invent the same invention, for the latter inventor to be entitled to the patent, she must demonstrate that she (1) was the first to conceive of the invention and (2) was reasonably diligent in reducing it to practice. The Federal Circuit recently ruled on what, exactly, “reasonable diligence” entails at the Patent Trial & Appeal Board (PTAB) in Arctic Cat Inc. v. GEP Power Products, Inc. (here)

Previous PTAB Opinions Designated Precedential

Yesterday, the Patent Trial & Appeal Board (PTAB) designated two older AIA trial decisions, and one recent decision, precedential. These three decisions follow last week’s Precedential Opinion Panel (POP) decision in Proppant Express Investments v. Oren Technologies, which held issue joinder was embraced by 35 U.S.C. § 315(c), but a matter of Board discretion.

Since the revision of its Standard Operating Procedure (SOP) for designating precedential and informative decisions (SOP2), it is expected that the Board will continue to expand upon the current number of precedential decisions.
