On Thursday, December 20th, the Court of Appeals for the Federal Circuit issued a nonprecedential decision in Vivint, Inc. v. Alarm.com, Inc. which affirmed aspects of three inter partes review (IPR) proceedings conducted by the Patent Trial and Appeal Board (PTAB) invalidating certain claims from three patents owned by Vivint. However, the Federal Circuit panel of Chief Judge Sharon Prost and Circuit Judges Kathleen O’Malley and Todd Hughes found an erroneous claim construction led the Board to uphold some of the challenged claims.

The Federal Circuit recently issued a nonprecedential opinion in Amazon.com, Inc. v. ZitoVault, LLC, affirming a decision by the Patent Trial and Appeal Board (PTAB) that e-commerce giant Amazon failed to prove a patent owned by security solutions provider ZitoVault was unpatentable. The Federal Circuit majority of Circuit Judges Kara Stoll and Kathleen O’Malley disagreed with Amazon’s that the PTAB erred in its claim construction. Dissenting, Chief Judge Sharon Prost wrote that she believed the PTAB’s analysis of a specific claim term was flawed, and she would have vacated the PTAB decision and remanded the case for further consideration. The patent-at-issue was ZitoVault’s U.S. Patent No. 6484257, titled System and Method for Maintaining N Number of Simultaneous Cryptographic Sessions Using a Distributed Computing Environment. Issued in November 2002, it claims a software architecture for conducting a plurality of cryptographic sessions over a distributed computing environment.

On Friday, November 9th, the Court of Appeals for the Federal Circuit issued a nonprecedential decision in NuVasive, Inc. v. Iancu, which vacated certain findings of the Patent Trial and Appeal Board (PTAB) in an inter partes reexamination proceeding involving a NuVasive patent covering a system and methods for minimally invasive surgical procedures. The Federal Circuit panel of Circuit Judges Pauline Newman, Raymond Chen and Todd Hughes determined that on the issue of secondary considerations the PTAB erred in finding no nexus between NuVasive’s claimed method and the surgical procedure actually commercialized by NuVasive. The panel also held that further fact-finding was required in order to determine whether an asserted prior art publication teaches a certain nerve-monitoring technique necessary to support the Board’s determination of obviousness. Therefore, the decision of the PTAB was vacated and the case remanded for further proceedings consistent with the Court’s opinion.

“It seems self-evident that the same patent contested in different tribunals should have its meaning – its boundaries – determined using the same standard,” Director Iancu said when discussing the final rules implementing the Phillips standard at the PTAB… Those few who were not pleased by the change have cited a believe that the change to the Phillips standard would usher in a return to lower quality patents. With a bit of a confrontational tone, Director Iancu took issue with that, finding the argument without merit.

On Tuesday, September 4th, the Court of Appeals for the Federal Circuit issued a precedential decision in Intellectual Ventures I LLC v. T-Mobile USA, Inc., et. al., vacating and remanding a grant of summary judgment entered by the district court finding the defendants in the case didn’t infringe a patent asserted by Intellectual Ventures. The Federal Circuit panel of Chief Judge Sharon Prost and Circuit Judges Kimberly Moore and Jimmie Reyna found that the district court had erred in its claim construction leading up to the grant of summary judgment in the case.

In its decision, the Federal Circuit noted that the PTAB is entitled to strike arguments improperly raised in a reply brief under 37 CFR § 42.23(b). However, the appellate court disagreed that Ericsson raised a new theory in its reply brief and thus the Board erred in not considering those portions of the reply brief. “The Board’s error was parsing Ericsson’s arguments on reply with too fine of a filter,” the Federal Circuit found. Ericsson’s petition for IPR described how a person with ordinary skill in the art would be familiar with the concept of interleaving. The CAFC further found that the PTAB’s error was exacerbated by the fact that the new claim constructions proposed by Intellectual Ventures after institution gave rise to the significance of interleaving in the proceeding. In light of this, the Federal Circuit found that Ericsson deserved an opportunity to respond to the new construction.

The proposed rule would adopt the narrower standard articulated by the Federal Circuit in Phillips v. AWH Corp., where the “words of a claim are generally given their ordinary and customary meaning,” which is “the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” 415 F.3d 1303, 1312-13 (Fed. Cir. 2005). Additionally, under the proposed approach, the Patent Office would construe patent claims and proposed claims based on the record of AIA proceeding, and take into account the claim language, specification, and prosecution history. In response to the Patent Office’s notice of proposed rulemaking, the New York Intellectual Property Law Association (NYIPLA) recently submitted comments endorsing the Patent Office’s proposed changes.

Congresswoman Lofgren is now opposing a rule change she previously endorsed as an original co-sponsor of a bill that would have changed the claim construction rule in exactly the same way proposed by Director Iancu… But how is adopting a rule that would have already been the law had Lofgren had her way possibly frustrate or disregard Congress? Of course, we aren’t supposed to ask that question. Once the “patent troll” boogeyman card is played everything else is supposed to fade away.

TF3’s patent-in-suit is for a “hair styling device” that automated the curling of hair. TF3 appealed the decision of the Board in an IPR requested by Tre Milano. Based upon its broad construction of certain claim terms, the Board held that two prior art references made the challenged patent claims invalid for anticipation. TF3 appealed. The Federal Circuit reversed the Board’s decision because it imposed a claim construction that was broader than the description in the patent specification. This enlarged the claims beyond their correct scope, even under a “broadest reasonable interpretation” standard. The Federal Circuit noted that “[a]bove all, the broadest reasonable interpretation must be reasonable in light of the claims and specification.”

On Monday, July 16th, the Court of Appeals for the Federal Circuit issued a precedential decision in Blackbird Tech v. ELB Electronics, which vacated an earlier judgment of non-infringement of a patent asserted by Blackbird in the District of Delaware. The Federal Circuit majority panel of Chief Judge Sharon Prost and Circuit Judge Kimberly Moore determined that the district court had erred at construing the claim term “attachment surface” in finding non-infringement of the asserted claims. Circuit Judge Jimmie Reyna dissented in this case.

On appeal to the Federal Circuit, Zeroclick argued that the district court erred in construing those two terms as means-plus-function limitations, an argument with which the Federal Circuit panel agreed. “Neither of the limitations at issue uses the word ‘means,’” Circuit Judge Hughes writes in his majority opinion. “Presumptively, therefore, [Section 112(f)] does not apply to the limitations.” Although Apple argued in the district court that the claims must be construed under Section 112(f), it provided no evidentiary support for its position. Although the court compared Apple’s arguments to Zeroclick’s objections, Judge Tigar did not point to any record evidence supporting the ultimate conclusion on Section 112(f) grounds.

Congresswoman Lofgren seems quick to forget that she was one of the original co-sponsors of the Innovation Act when it was introduced into the House back in February 2015. Had the Innovation Act passed, it would have required patents challenged in IPR proceedings to be construed in the exact same manner that a district court would have required in a civil action to invalidate the patent. So, it seems Lofgren was for the Phillips standard and eliminating BRI before she was against it.

found it disturbing that the Director Iancu would circumvent the prerogative of Congress with recently announced proposed PTAB claim construction changes, though she admitted the decision wasn’t unlawful. She expounded for several minutes on issues of res judicata, which could tie the hands of the PTAB in light of district court or U.S. International Trade Commission (ITC) decisions regarding patent validity. “[This] would completely blow up what we were trying to do as a Congress,” Lofgren said. “It looks to me that the people who disagreed with [the AIA] and lost in the Congress, they went to the Supreme Court, they lost in the Supreme Court, and now they’re going to you, and you are reversing what the Congress decided to do and what the Court said was permissible to do.”

The Federal Circuit found that the Board failed to provide sufficient explanation for its obviousness finding, instead using a conclusory approach that asked whether the missing limitation resulted from “ordinary creativity” of a skilled artisan. According to the panel majority, the question of whether the claims resulted from ordinary creativity was akin to asking whether the claims were obvious as a result of common sense. Therefore, the Federal Circuit began by returning to it’s 2016 ruling in Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355 (Fed. Cir. 2016), which dealt with the proper use of common sense as part of an obviousness rejection.
