Would a “Mini-Markman” Have Helped Patent Owners?

A long time ago, in a galaxy, far, far away….the Patent Trial & Appeal Board (PTAB) considered implementing a Markman style claim construction procedure it labeled a “Mini-Markman.” The idea, along with others was the result of a 2015-16 listening tour conducted by the agency under former USPTO Director Michelle Lee. The listening tour stopped at several locations across the U.S. to collect public feedback on AIA trial proceedings. The tour culminated in a draft rule package that contained a number of interesting ideas. Needless to say, that rule package was abandoned and never saw the light of day (for reasons unknown)

As we move into the new year and look forward to coming PTAB rule packages on discretionary denials and rehearing practices, I revisit this old idea in view of the never ending dialog on reforming the PTAB.…

Pursuing Different Constructions Before the PTAB & Court?

Since the PTAB started applying the Philips standard for claim construction, petitioners have put a lot more thought into their proposed claim constructions. This is because it is no longer possible to point to the PTAB’s use of the broadest reasonable interpretation (BRI) as the basis for a different construction.

Now, petitioners are very careful to be consistent with disputed terms.  But, what happens if a petitioner argues for a broader construction at the PTAB, then argues for a more narrowed construction in the district court?

CAFC Refuses Remand on 112 6th Deficiencies

When challenging claims at the Patent Trial & Appeal Board (PTAB), Rule 42.104(b)(3) requires a Petitioner to identify the specific portions of a challenged patent’s specification that describe the structure corresponding to a claim’s means-plus-function claim feature.  Of course, if a petitioner fails to do so, the Board will reject Petitioner’s challenge for failing to comply with the Rule.  To the frustration of petitioners, however, where that failure is based upon the shortcomings of the challenged patent itself, the PTAB is  precluded from officially making such an indefiniteness determination.  Instead, the Board will simply conclude that the rule has not been satisfied.

A week back, the Federal Circuit reiterated this shortcoming of the IPR statutes. …

PTAB 2018: A Year of Agency Recalibration

The Patent Trial & Appeal Board (PTAB) stole much of the 2018 patent law spotlight. From landmark Supreme Court decisions such as Oil States and SAS Institute, to significant en banc Federal Circuit decisions in WiFi-One, PTAB practice evolved more in 2018 than in any prior year. That said, the most impactful 2018 changes for practitioners were driven by the agency.

Under the pro-patent leadership of Director Iancu, the agency is expected to drive still further change in 2019.

Assignor Estoppel Precluded by AIA Statutes…But What of Other Equitable Defenses?

The doctrine of assignor estoppel bars the assignor of a patent from challenging the validity of the patent after it is assigned. In considering this defense to an AIA trial proceeding, the Patent Trial & Appeal Board (PTAB) had consistently held that this common-law doctrine is subject to abrogation by statute, and that the AIA statutes do exactly that. The Federal Circuit recently agreed.

However, the Board has considered and applied other equitable defenses. For example, the Board has applied waiver (prior to the Federal Circuit’s determination that tribal immunity did not apply to the PTAB). Thus, equitable defenses that do not conflict with the AIA statutes may be leveraged.

One equitable defense that could become more prominent going forward —given the alignment of claim construction standards between the PTAB and courts— is judicial estoppel.…
