Judicial Clerkship

Law Clerk to the Honorable David Folsom, United States District Court for the Eastern District of Texas (2009-2010)

John P. Lahad

I joined Susman Godfrey in 2010 after a year-long clerkship with the Honorable David Folsom, then-Chief Judge of the United States District Court for the Eastern District of Texas.  Since then I have represented plaintiffs and defendants in several matters involving intellectual property, securities, oil and gas, managed care, and general commercial disputes.

With Joseph Grinstein, I represented PACT XPP Technologies, GMBH in its patent infringement suit against Xilinx, Inc. and Avnet, Inc., leading players in the field programmable gate array industry, in the Eastern District of Texas, Marshall Division.  At the end of the week-long trial before Judge Payne in May 2012, the jury found that Xilinx and Avnet infringed PACT patents, rejected the defendants’ claim the patents were invalid, and found Xilinx’s infringement to be willful.  At trial, I handled damages, putting on our expert witness and cross-examining defendants’ expert witness.  In September 2013, Judge Payne entered judgment on the verdict totaling approximately $44 million—including enhanced damages for Xilinx’s willful infringement and an award of attorneys’ fees.  The case subsequently settled for a confidential amount.

With Chanler Langham, I represented Bellaire, Texas-based Mobius Medical Systems, LP in its suit against Sun Nuclear Corporation.  Mobius and its founder Dr. Nathan Childress came to me after a former exclusive distributor released a competitive product that incorporated Mobius’s confidential and proprietary trade secrets.  We filed suit and immediately obtained a preliminary injunction enjoining Sun Nuclear from promoting, marketing, and selling the offending product. The case settled about a year later.  Part of the settlement included this permanent injunction.

With Justin Nelson, Parker Folse, Max Tribble, and others at Susman Godfrey, I represented Rockstar Consortium US LP and Netstar Technologies LLC in their patent infringement suit against Google in the Eastern District of Texas.  Rockstar and Netstar alleged infringement of several patents related to search-related advertising. I handled several phases of the litigation. In addition to defending key witnesses, I helped lay the foundation for favorable Markman rulings. The case settled before trial.

With Brooke Taylor and others from Susman Godfrey, I currently represent Intellectual Ventures I, LLC in a patent infringement suit against Symantec Corporation and Trend Micro, Inc. pending in the District of Delaware before the Hon. Leonard Stark.  The patents-in-suit involve technology related to email and network security.  I embraced my role as the technology guru in this matter, pored through thousands of documents, deposed several developers and programmers, and learned the inner workings of defendants’ accused products.  Armed with this deep understanding, I took several key depositions in the case, including the deposition of Trend Micro’s founder and CEO, Ms. Eva Chen.  At trial against Symantec, I handled our invalidity case, cross-examining Symantec’s expert and presenting our rebuttal expert. The jury maintained the validity of each patent at trial. The case is currently on appeal to the Federal Circuit.

With Jacob Buchdahl and Arun Subramanian, I represented biomedical device innovator Globus Medical in a patent infringement suit brought by Tyler, Texas-based Flexuspine, Inc. Flexuspine claimed that Globus’s intervertebral spacers infringed its patents. We tried the case before Judge Rodney Gilstrap in Tyler in August 2016 and obtained a full defense victory.  During and before trial, I handled every aspect of the liability case, including infringement and invalidity, and at trial I put on our technical expert and cross-examined Flexuspine’s expert.

I truly enjoy and excel at high-stakes intellectual property cases, but I have augmented my intellectual property expertise with several non-intellectual property matters.

For example, with Geoffrey Harrison and Kenneth McNeil, I represent Maghreb Petroleum Exploration S.A. and Mideast Fund for Morocco Ltd. in a suit to enforce a $122 million judgment from a court in the Kingdom of Morocco against Patron Tequila co-founder John Paul DeJoria under Texas’s version of the Uniform Foreign Country Money Judgments Recognition Act. On September 30, 2015, the Fifth Circuit reversed the trial court’s determination that the Morocco Court judgment should not be recognized. Read the Fifth Circuit’s opinion here.  In securing this result, I read and analyzed nearly every publicly available decision in the U.S. involving the Uniform Recognition Act. I hope to apply this deep understanding and experience with the Act to other foreign judgment enforcement matters.

With Brian Melton, Jonathan Ross, and Chanler Langham, I represent local healthcare provider Humble Surgical Hospital in a suit against health insurance giant Cigna. In this ERISA case, Cigna claims that it should not have to pay for over $30 million dollars’ worth of medically necessary procedures provided by Humble to Cigna members, labeling Humble a “fee-forgiver.” In January 2016, the Honorable Judge Hoyt of the Southern District of Texas presided over a bench trial. In June 2016, Judge Hoyt issued his ruling, finding in our favor on every issue and awarding $11.4 million in damages, $2.3 million in ERISA penalties, and attorneys’ fees. Read Judge Hoyt’s opinion here.

With Kenny Marks, Jonathan Ross, and others at Susman Godfrey, I represented the trustee of the Circuit City Liquidating Trust as an opt-out in an anti-trust class action matter regarding cathode ray tubes.  We alleged that various manufacturers of cathode ray tubes used in televisions and computer monitors engaged in anti-competitive activity in violation of U.S. Anti-trust laws.  The case settled before trial.

With James Southwick, I represented a group of Beaumont, Texas-area plaintiffs in a FINRA arbitration involving the Medical Capital Ponzi scheme. My clients collectively invested millions of dollars in Medical Capital’s allegedly bogus notes.   Mr. Southwick and I were able to obtain a favorable settlement for our clients, who thought they’d lost it all.

In 2014, 2015 and 2016, I was chosen a Rising Star by Law & Politics Magazine (Thomson Reuters).

When not practicing law, I enjoy spending time with my beautiful and supportive wife and our three wonderful children.
