“In a time of international crisis, Jackson Walker really helped us out. In addition, JW has given us immediate attention through the years on a variety of business and IP issues – even after hours and weekends. In “bet the business” patent litigation, Jackson Walker fought back effectively and efficiently with technical and legal expertise, saving us from what would have otherwise been an expensive trial where the expected recovery would have been far less than the cost of litigation. I strongly recommend them to handle important patent litigation against competitors. We view the JW team as an essential part of our business.”

— Alan Mead, CEO, Applied Concepts

Biography

Chris Rourk, an inventor of an adiabatic quantum computing device (U.S. 10,817,780), is a thought leader in artificial intelligence legal matters, with 10 years’ field experience as a former engineer and over two decades of diverse legal experience. His practice encompasses all aspects of intellectual property, as well as corporate transactions, commercial litigation and other complex interdisciplinary matters for clients across industries.

Chris has prosecuted 600+ patents to issuance in diverse technological fields such as nanotechnology devices, semiconductor systems and devices, artificial intelligence, radio frequency systems and devices, analog systems and devices, software, telecommunications systems and devices, medical devices, image data processing systems and devices, and consumer electronics. One area in which Chris excels is in the use of strategic post-grant proceedings to invalidate patents that have been or might be asserted against clients. These proceedings allow improperly-granted patent claims to be attacked in the patent office, to save clients the expense and stress of district court litigation.

As an engineer, Chris developed numerous technical proficiencies while working for Bechtel Power Corporation on-site for a major power plant construction project, where he was involved with designing and installing telecommunications, control and power systems components. He then worked for Westinghouse Electric Corporation, where he designed large turbine generators and extensively applied three-dimensional finite element computer models to new and existing designs. This unique background gives Chris specific insights into solutions for many business problems encountered by clients, as well as preventative measures and strategies for avoiding those problems.

During law school, Chris worked for the U.S. Nuclear Regulatory Commission, where he performed research and directed research at a number of national laboratories into issues pertaining to nuclear power safety, including probabilistic risk assessment computer models of nuclear power plant safety systems.

Patents Are for the Weak? | Asia IP Magazine

For Jackson Walker partner Christopher Rourk, patents are, to a certain extent, for the weak. The reason for this is that small firms and individual inventors are inherently weaker than companies that are larger and better-positioned capital-wise.

“Small companies and individual inventors can develop important innovations that can be easily copied by larger, well-capitalized companies and should rely on patents to increase their leverage in the highly-competitive commercial marketplace,” he noted.

Apple Watch Might Be Banned for Sale in the United States Due to Patent Infringement | Asia IP

Jackson Walker partner Christopher Rourk spoke with Asia IP about a potential ban on the sale of the Apple Watch Series 6 after Masimo, a global medical technology corporation, asserted 10 patents against Apple in a California district court and sought an import ban before the U.S. International Trade Commission. In the article, Chris noted, “It is possible that Masimo might settle at this point on less than favorable terms in order to avoid a decision from the PTAB that invalidates some or all of its challenged patents, but based on its past behavior, it seems more likely that Masimo would be prepared to go to trial before settling. Apple likewise has a history of fighting patent infringement lawsuits, although it is noted that both companies have much at stake in the current dispute, so settlement prior to trial in any of these matters is certainly possible.”

However, it is not uncommon for such matters to be resolved through a settlement and patent portfolio license prior to a verdict being rendered, with net payments going to the party with the stronger portfolio position.”

Chris was the lead briefing attorney for the appellant in In re Magnum Oil Tools International, 829 F.3d 1364 (Fed. Cir. 2016), one of the first cases to result in a full reversal of the Patent Trial and Appeal Board from a decision in an inter partes review, and which has been cited in subsequent court decisions over 600 times. The Federal Circuit agreed with Chris’ argument that it was improper to shift the burden of proof to the patent owner to prove the validity of the challenged patent.

Chris has handled a number of high-profile patent litigation matters, including filing the lawsuit that resulted in the Federal Circuit decision in BMC v. Paymentech, 498 F.3d 1373 (Fed. Cir. 2007), which provided controlling precedent on the question of joint infringement of patent claims and which has been cited in subsequent court decisions over 300 times. His patent prosecution work has also been cited as exemplary by the U.S. Patent and Trademark Office and has withstood attack in district court litigation and post-grant challenges.

Career Highlights

Chris was the lead briefing attorney for the appellant in In re Magnum Oil Tools International, 829 F.3d 1364 (Fed. Cir. 2016), one of the first cases to result in a full reversal of the Patent Trial and Appeal Board from a decision in an inter partes review, and which has been cited in subsequent court decisions over 600 times. The Federal Circuit agreed with Chris’ argument that it was improper to shift the burden of proof to the patent owner to prove the validity of the challenged patent.

Chris has handled a number of high-profile patent litigation matters, including filing the lawsuit that resulted in the Federal Circuit decision in BMC v. Paymentech, 498 F.3d 1373 (Fed. Cir. 2007), which provided controlling precedent on the question of joint infringement of patent claims and which has been cited in subsequent court decisions over 300 times. His patent prosecution work has also been cited as exemplary by the U.S. Patent and Trademark Office and has withstood attack in district court litigation and post-grant challenges.
