In a noteworthy decision that sheds light on the interplay between patent disclaimers and post-grant reviews, the Patent Trial and Appeal Board (PTAB) recently denied institution of a challenge to an Intex Marketing patent while declining to enter adverse judgment against the patent owner.

On June 15, 2024, Bestway (USA), Inc. petitioned for post-grant review of all 24 claims in U.S. Patent No. 11,959,512 B2. In what proved to be a strategic maneuver, Intex Marketing responded by filing a statutory disclaimer of all challenged claims, effectively surrendering their rights to the patent. This move raised an important question for the Board: should they simply deny institution, or take the additional step of entering adverse judgment against Intex?  In its October 28, 2024 decision, the Board opted to take the former approach.

The distinction between these two outcomes carries significant implications for patent owners. An adverse judgment would trigger estoppel provisions preventing Intex from obtaining or enforcing patents with substantially similar claims. This became particularly relevant because the ‘512 patent belongs to a family that includes three other granted patents and pending continuation applications.

In deciding against adverse judgment, the Board emphasized several crucial factors. First, Intex had never asserted or threatened to assert the ‘512 patent against Bestway. While Bestway argued it had incurred “significant expense” preparing its petition in response to what it characterized as “harassing” cease-and-desist letters regarding related patents, the Board found this insufficient justification for adverse judgment.

In a significant ruling that clarifies the standards for expert disqualification in patent litigation, the U.S. District Court for the Eastern District of California has denied E. & J. Gallo Winery’s motion to disqualify Dr. Mark Greenspan, an expert witness for Vineyard Investigations. The December 2, 2024 order provides crucial guidance on the treatment of technical information in expert disqualification analyses and the interpretation of protective orders in patent cases.

Case Background

The underlying dispute involves Vineyard Investigations’ allegations that Gallo infringed patents related to variable rate drip irrigation systems. The controversy arose when Vineyard Investigations designated Dr. Greenspan, a former Gallo employee, as an expert witness. Dr. Greenspan had worked for Gallo between 1996 and 2005 as an irrigation specialist and Winegrowing Research and Development Manager.

Key Legal Framework

The court’s analysis centered on two potential grounds for disqualification, as articulated in the order:

“There are two relevant bases on which Defendant moves Dr. Greenspan be disqualified: (1) an exercise of a trial court’s inherent discretion and (2) pursuant to Section 2.6 of the protective order.”

The court emphasized that “disqualification is a drastic measure that courts should use reluctantly and rarely,” setting a high bar for excluding expert testimony.

In a recent high-stakes patent litigation case, a protective order, filed on November 22, 2022, was put in place to safeguard confidential information during the course of the legal proceedings.  The defendant asserted that the plaintiff’s legal team had struggled to adhere to the protective order’s strict guidelines.

The first alleged violation involved a trial transcript containing sealed proceedings, which was sent from an associate at the plaintiff’s law firm, Williams & Connolly, to an associate at Morrison & Foerster, who is representing the plaintiff in separate IPR proceedings. This disclosure took place on July 18, 2023.

The second incident revolves around the plaintiff’s closing slide no. 298, which contained the defendants’ confidential Yesafili formulation. An associate at Williams & Connolly sent this slide to the plaintiff’s in-house counsel and to outside counsel in Canada. From there, the slide was disseminated to other members of the plaintiff’s in-house counsel team and to various international law firms.

The third and perhaps most concerning alleged violation involves the defendants’ BLA and other confidential information. The plaintiff’s in-house counsel sent this sensitive data to the Liad Whatstein firm in Israel, which handles patent litigation. Continue reading

In a recent discovery dispute in a patent infringement case, the district court denied the defendant’s motion to compel the plaintiff to produce certain inventor emails that were withheld on the basis of the work product doctrine. The key issue was whether the plaintiff demonstrated that the emails, exchanged between the two inventors of the asserted patents from 2016-2018, were prepared in anticipation of litigation. The litigation ultimately commenced in February 2022.

The district court acknowledged that evidence pointed to by both sides benefitted their respective positions–the defendant highlighted facts suggesting the inventors’ work was not in anticipation of litigation, while the plaintiff provided contrary evidence. Ultimately, the district court found the plaintiff’s showing sufficient to meet its burden and justify the work product protection.

Key evidence cited by the district court included:

  1. An inventor’s testimony that he began investigating potential infringement in November 2015 with the assistance of outside counsel.
  2. The inventor provided information to outside counsel from 2016-2020 to assess possible infringement.
  3. Starting November 2015, the inventor implemented measures to preserve documents related to the patents and defendant.
  4. Testimony from the outside attorney that he had previously advised the plaintiff about potential litigation involving the patents at issue.

In the ongoing patent infringement case between Acceleration Bay LLC and Activision Blizzard Inc., the district court recently issued an order resolving several important evidentiary disputes between the parties. This order provides guidance on the admissibility of various categories of evidence that will impact the damages case at the upcoming trial.

Here are the key takeaways:

Survey Evidence Allowed for Limited Purpose

The court permitted Acceleration Bay to use Activision’s own customer surveys for the limited purpose of showing that the allegedly infringing large multiplayer game modes in Call of Duty are of equal or greater importance to customers compared to the non-infringing small game modes. Nonetheless, the district court reiterated its exclusion of the plaintiff’s damages expert’s opinions apportioning royalties based primarily on this survey evidence, finding that while the surveys can demonstrate the significance of the accused modes, they cannot directly calculate the royalty damage amount.

Evidence of Foreign World of Warcraft Sales Permitted

The district court allowed Acceleration Bay to present evidence of Activision’s foreign sales revenues for the World of Warcraft game. The plaintiff’s theory is that the infringing U.S.-based server system supports foreign players in North and South America. The district court found that as long as Acceleration Bay provides evidence linking the foreign sales to the accused domestic server system, the foreign revenue numbers can be admitted, even if conditionally at first.

In a recent development in patent litigation, the district court has granted a motion to dismiss counterclaims in a case involving U.S. Patent No. 10,519,668 (“the ‘668 Patent”). The decision sheds light on the importance of adhering to meet and confer obligations, as well as the consequences of non-compliance.

Background:

The defendants in this case had asserted counterclaims, including declaratory judgments of invalidity and non-infringement of the ‘668 Patent, breach of contract, fraud, unjust enrichment, and constructive trust.  On October 31, 2023, the district court granted the defendants’ Motion for Summary Judgment of non-infringement of the ‘668 Patent, marking a significant milestone change in the proceedings.

Subsequent Events:

Following the district court’s decision, the defendants’ counsel sought to engage in a meet and confer with the plaintiff, Upstream, regarding the possible dismissal of the counterclaims without prejudice. Despite making multiple attempts to contact Upstream’s counsel between March 19 and 27th, no response was received. Consequently, the defendants proceeded to file a motion to dismiss their counterclaims on March 29, 2024. Continue reading

In the ongoing case of Inmar Brand Solutions, Inc. v. Quotient Technology Inc., the district court was tasked with conducting an analysis under the Supreme Court’s two-step test in Alice Corp. v. CLS Bank International to determine whether Inmar’s patented coupon-processing system, exclusively licensed from Intelligent Clearing Network, Inc. (ICN), was entitled to patent protection. Under the Alice framework, the district court must first ascertain whether claims are directed towards patent-ineligible subject matter, such as abstract ideas. If so, the district court proceeds to the second step, wherein it evaluates whether the claims contain an inventive concept that transforms the abstract idea into a patent-eligible application.

Quotient contends that the patents asserted by Inmar are invalid and directed towards a patent-ineligible abstract idea: namely the processing of coupons on a remote server. According to Quotient, the claims lack an inventive concept and merely recite generic computer components.

Inmar opposes this characterization, and contends that the claims represent an improved coupon processing architecture that significantly reduces fraud and cannot be accomplished by humans.

As explained by the district court, the primary concern underlying this argument is the concept of preemption, which aims to prevent the granting of a monopoly over an abstract idea that could impede innovation. While the Supreme Court in Alice did not provide precise contours for what constitutes an abstract idea, subsequent Federal Circuit decisions have shed light on this issue. Continue reading

The crux of this case revolves around a dispute over patent infringement, trade secret misappropriation, and unfair competition filed by Nielsen (or Plaintiff) against Hyphametrics (or Defendant). At the heart of the issue in this motion were specific documents – experimental reports. These reports were initially produced by Hyphametrics to Nielsen but were later retracted under the assertion of work product protection.

The Memorandum Order issued by the court dissected the arguments presented by both parties and presented the court’s rationale for its ruling on Nielsen’s motion to compel Hyphametrics to produce the disputed documents. The court began by addressing Hyphametrics’ intentional production of certain reports to Nielsen. Despite Hyphametrics’ claim that the documents were mistakenly believed to be unprotected by the work product doctrine, the court noted that the intentional release of these documents nullified any work product protection. The court emphasized that the mistaken belief in their protection status cannot serve as a valid basis for claiming inadvertent production.

The court explained that Defendant’s prior counsel (“prior counsel”) produced three reports at issue here to Plaintiff. “When prior counsel did so, it knew all of the facts one would need to know to understand that, under the law, those documents were protected by the work product doctrine. A document is protected by the work product doctrine if it is prepared in anticipation of litigation or trial by a party or its representative. Fed. R. Civ. P. 26(b)(3)(A). It is undisputed here that the reports fit this bill, and prior counsel knew this when they intentionally produced the reports.” As a result, the court concluded that Defendant therefore waived any work product protection for the reports by intentionally producing them here.

The legal battle between GoTV Streaming, LLC and Netflix, Inc. continues to unfold, captivating the streaming industry and legal observers alike. In a recent development in the case, the district court issued an order denying Netflix’s motion to compel GoTV Streaming to disclose its third-party funding related documents. This ruling adds a new layer of complexity to the proceedings and sheds light on the district court’s perspective regarding the use of third-party funding in high-stakes litigation.

Netflix sought to compel GoTV Streaming to disclose its third-party funding documents, arguing that the information was essential to understanding the financial dynamics behind the lawsuit. They contended that such funding arrangements might create conflicts of interest, influence litigation strategy, or affect the plaintiff’s ability to meet potential damages awards. Netflix believed that these documents were critical for a comprehensive assessment of the case and ensuring a fair trial.

In the order, the district court denied Netflix’s motion to compel GoTV Streaming to disclose its third-party funding documents. The district court acknowledged the potential relevance of the information requested by Netflix but found that Netflix did not meet the standard required for disclosure. The district court reasoned that the mere possibility of conflicts of interest or influence on litigation strategy was not sufficient grounds to compel disclosure without stronger evidence of impropriety.

In the case of Speyside Medical, LLC v. Medtronic CoreValve LLC et al, the district court recently granted the defendants’ motion to compel the plaintiff, Speyside Medical, to produce information regarding its members and litigation funder. The district court found such information relevant, emphasizing the importance of understanding the precise financial stake held by the plaintiff’s members in the outcome of the lawsuit.

Speyside Medical, LLC filed a lawsuit against Medtronic CoreValve LLC and other defendants. As the litigation unfolded, the defendants sought to compel Speyside Medical to disclose information about its members and its litigation funder. They argued that this information was crucial to understanding potential biases that may arise from financial interests in the case outcome.

In granting the defendants’ motion to compel disclosure, the district court stated, “Surely whether Plaintiff’s members have a financial interest in the outcome of this lawsuit is, as Defendants suggest, relevant to bias for purposes of future cross-examination of the members.” The district court emphasized the significance of understanding the precise financial stake held by the plaintiff’s members, considering the complexity of the financial arrangements involved.
