Collateral Estoppel Prevents Reexam Claim from being Enforced

On November 19, 2014, the United States Court of Appeals for the Federal Circuit issued a decision in e.Digital Corporation v. Futurewei Technologies, Inc. e.Digital appealed from a judgment of non-infringement made by the U.S. Federal District Court for the Southern District of California. The district court based its determination of non-infringement on the fact that e.Digital was collaterally estopped from seeking a construction of a claim limitation in e.Digital’s U.S. Patent Nos. 5,491,774 and 5,839,108 different from another court’s previous construction of the same limitation in the ’774 patent.

The Federal Circuit, with Judge Moore writing and joined by Judges O’Malley and Reyna, held that the district court correctly applied collateral estoppel to the ’774 patent, but improperly applied the doctrine to the unrelated ’108 patent.

To understand the ruling in this case one must first look at the prior case that construed the critical claim. Previously, in a litigation in the United States Federal District Court for the District of Colorado, e.Digital asserted claims 1 and 19 of the ’774 patent. The ’774 patent discloses a device with a microphone and a removable, interchangeable flash memory recording medium that allows for audio recording and playback. Asserted claims 1 and 19 recited “a flash memory module which operates as sole memory of the received processed sound electrical signals.” The district court construed the sole memory limitation to require “that the device use only flash memory, not RAM or any other memory system” to store the “received processed sound electrical signals.” The district court based its construction on the written description of the ’774 patent and its determination that the use of RAM had been disclaimed during prosecution. With this claim construction decided, the parties stipulated to a dismissal of the case with prejudice.

Paying Ransom to Patent Trolls Is a Mistake

I have absolutely no problem with enforcing patent rights, and frankly I don’t think it should matter how the patents were acquired, but there is something exceptionally seedy about the use of shell companies going after competitors, or large tech companies selling to known patent trolls. They complain about the troll problem in the halls of Congress on the one hand, but use them to their advantage on the other hand.

The question should be whether there is infringement of a solid patent. If there is a solid patent and there is infringement, then there should be recourse, period. Having said that, it would be naive to pretend that there is not real evil lurking in the patent infringement realm. Stories of $500 to $1,000 offers to settle and avoid patent infringement litigation that would cost millions of dollars to defend abound. False and misleading demand letters prey on unsophisticated businesses.

Talking Patent Litigation with Ray Niro

Ray Niro is one of the most well-known patent litigators in the country, and the attorney who was famously dubbed “a patent troll” some 14 years ago, marking the first time the term was used. See The Man They Call the Patent Troll. The label “patent troll” doesn’t really fit Niro, if you ask me, because he hs been extraordinarily successful at proving that large corporations have infringed valid patents, sometimes on fundamentally important innovations. In fact, Niro has been a champion for independent inventors and small businesses who have created some of the most revolutionary inventions. WiFi is an example.

Over the past few years, I have gotten to know Ray…he has written several op-ed articles for IPWatchdog.com…and about once a year we catch up in an ‘on the record’ interview. I spoke with Niro at length on June 25, 2014. The complete transcript of my interview with him is available at A Conversation with Patent Defense Litigator Ray Niro.

What prompted this interview was seeing an announcement that he and his firm are now offering flat fee defense representation in patent litigation matters. Ray Niro defending a patent infringement case? I have to admit I didn’t realize he did defense work, so I wanted to talk to him about this new business model. We discuss this at length during the first segment of our conversation.

Breaking the Cycle – Stand Up and Fight Patent Trolls

The term “patent troll” conjures up all kinds of images and ideas, but there is no universally accepted definition of who is a patent troll. This has led many to recognize that, by and large, if you are being sued for patent infringement, it will likely be your belief that you are being sued by a patent troll. But obviously not everyone who sues for patent infringement is a patent troll, and neither is every plaintiff who loses a patent infringement lawsuit. There will be reasonable assertions that ultimately result in a defendant prevailing for a variety of reasons. Thus, a patent troll really should be identified by litigation tactics. A patent troll is one who is abusing the judicial process and leveraging judicial inefficiencies to obtain unwarranted settlement payments.

In determining whether one is a patent troll, I don’t think it should matter how the patents were acquired. If there is infringement of substantial patents, then there should be recourse. Having said that, it would be naive to pretend that there is not real evil lurking in the patent infringement realm. Stories of $500 to $1,000 offers to settle and avoid patent infringement litigation that would cost millions of dollars to defend abound. Some courts have openly acknowledged what feels like “extortion-like” activity. See Indicia of Extortion and Troll Turning Point?

Contempt Proceeding Fails on Colorable Difference Prong

Last week, the United States Court of Appeals for the Federal Circuit issued a decision in ncCUBE Corporation v. SeaChange International, dealing with the failure of the district court to find SeaChange in contempt for violating a permanent injunction.

ARRIS (formerly nCUBE) commenced the present litigation on January 8, 2001, alleging the infringement of certain claims of U.S. Patent No. 5,805,804 (“’804 patent”), which discloses and claims a media server capable of transmitting multimedia information over any network configuration in real time to a client that has requested the information. The patented technology allows a user to purchase videos that are then streamed to a device such as a television.

On May 28, 2002, the jury returned a verdict in ARRIS’s favor, finding that SeaChange willfully infringed the asserted claims in the ’804 patent. The Federal Circuit later affirmed the jury verdict and the district court’s subsequent decision to enhance the damages award. Subsequent to the Federal Circuit affirmance, the district court entered a permanent injunction enjoining SeaChange from “making, using, selling, or offering to sell… the SeaChange Interactive Television System… as well as any devices not more than colorably different therefrom that clearly infringe the Adjudicated Claims of the ’804 patent.”
