N.D. and E.D. Tex. Courts Find Waiver of Venue Defense Notwithstanding TC Heartland Decision

The Federal Circuit recently clarified the requirement for work disclosed in a reference to qualify as “by another” under pre-AIA Sections 102(a) and (e), holding that there must be complete inventive identity between the information disclosed in the asserted reference and the inventors named on the relevant patent. 

The District Court for the Northern District of California recently granted a defendant’s motion to bifurcate, ordering that issues related to PGR estoppel should be decided in a bench trial, while the remaining issues in the case should proceed to a jury trial.

The Northern District of Iowa recently held that a defendant’s motion for partial summary judgment of invalidity was barred after the PTAB issued final written decisions, regardless of when the motion was filed. The defendant filed its motion before the final written decisions were issued, but the court rejected the defendant’s argument that the timing of the motion insulated it from estoppel.

In a recent final written decision, the PTAB determined that a reference patent was not prior art, despite the petitioner’s post‑filing attempt to correct its petition. While the petitioner argued that it intended to rely on the patent application’s earlier date of publication, both the corrected petition and the expert declaration continued to reference the issued patent rather than the published application.

The USPTO Director recently granted a petitioner’s request for rehearing of the decision discretionarily denying institution of inter partes review, ultimately vacating the original decision, and referring the petition to the board for an institution decision.

In considering claims to a method of reducing cardiovascular events, the Federal Circuit held that the term a “clinically proven effective” amount did not render the claims patentable over the prior art. Specifically, the Federal Circuit held that the “clinically proven effective” amount, whether limiting or not, could not be used to distinguish the prior art because the claims also specified the exact amount of the drugs to be administered in the method. The Federal Circuit also rejected patentee’s evidence of unexpected results because that evidence was tied solely to the “clinically proven effective” limitation.

The Federal Circuit reversed a district court’s denial of judgment as a matter of law on non-infringement, thereby setting aside a $106 million jury verdict, after holding that prosecution history estoppel barred the patentee from asserting infringement under the doctrine of equivalents.

A magistrate judge in the District of Delaware issued a Report and Recommendation, that found the sole asserted claim was a “single means” claim and therefore invalid for lack of enablement. In reaching that conclusion, the magistrate judge rejected the patentee’s argument that the preamble of the claim disclosed a second element that satisfied the combination requirement of Section 112, paragraph 6 because the preamble simply recited a descriptor of the very apparatus that was the subject of the means-plus-function limitation in the body of the claim. The district court judge presiding over this case has scheduled a hearing to review the magistrate’s ruling.
