Chair, Patent Office Trials Group
Minneapolis Lawyer Cyrus Morton


Mr. Morton is a Partner and Chair of the Patent Office Trials Group at Robins Kaplan. A trial attorney whose complex litigation practice has included an emphasis on patent litigation since 1998, he counsels clients on all aspects of IP-related litigation. 

Mr. Morton commonly works on both sides of the “v.” His representation of everyone from small companies and solo inventors to large corporate clients includes: 

  • Trial judgements and licensing campaigns including $100M, $89M, $30M, $19M, $12M and $7.9M. 
  • Representation of major companies such as Medtronic, Trane Technologies, Ingersoll Rand, Asahi Kasei, Promega, Polaris, KLA-Tencor, Toro, Hunter Douglas, Cardiovascular Systems Inc., Anderson Corporation, and more.
  • National recognition for litigation and post-grant proceedings by Benchmark Litigation and IAM 1000, as well as being named an “Intellectual Property Trailblazer” by The National Law Journal

Mr. Morton’s PTAB practice has led him to become the first, and still only, attorney in the country to handle all four types of post-grant proceedings under the America Invents Act. He has also been lead counsel in well over 100 IPRs. His past experience as a patent attorney, combined with handling numerous patent litigation disputes with co-pending reexaminations, makes him ideally suited to lead this practice area.

Prior to becoming a lawyer, Mr. Morton saw the patent system from the inventor’s side. While working at 3M Company, he co-authored three Records of Invention and was a named inventor on U.S. Patent No. 5,858,624, titled Method for assembling planarization and indium-tin-oxide layer on a liquid crystal display color filter with a transfer process.

Finally, Mr. Morton has significant pro bono experience. His work includes a two-week trial representing a guardian ad litem and successfully terminating parental rights so three children could be adopted into a new and safe home, and a Federal Court bench trial representing a mother accused of international child abduction in a Hague proceeding, and successfully defeating a petition to return her two minor children to their father in Peru because the children would face a grave risk of harm. Mr. Morton currently focuses his pro bono time mentoring junior lawyers representing women in need of Orders for Protection (OFPs), in connection with the Safety Project at


Crystal IS, Inc. v. Nitride Semiconductors Co. (N.D.N.Y. 1:12-CV-0606): Counsel for declaratory judgment plaintiff Crystal IS, a manufacturer of Ultraviolet LED semiconductors, in defense of patent infringement allegations.

Trane v. Harrison Energy Partners: Sued HEP on behalf of Trane for breach of contract and theft of trade secrets in the Eastern District of Texas (Texarkana). The case involved a former Trane independent sales office that terminated with Trane but continued to use Trane’s servicing software post-termination and developed and sold different software containing Trane proprietary information.

Case settled literally on the courthouse steps just prior to picking a jury.

Promega Corporation v. Applied Biosystems, LLC, Life Technologies Corporation, and California Institute of Technology: Judge Richard A. Posner ruled in favor of our client, Promega Corporation, in a suit that it initiated against one of its competitors. In an opinion dated June 12, 2013 from the U.S. District Court for the Northern District of Illinois, Judge Posner ruled that certain claims of U.S. Patent No. RE43,096, asserted against Promega, are invalid. Promega prevailed in its arguments that the claims of the ’096 patent were invalid due to the breadth of the claim constructions that Defendants sought and obtained. Certain asserted claims were invalid for lack of written description support. While the patent describes an improvement to DNA sequencing, the breadth of the claims encompassed technologies that Caltech did not invent, including the PCR-based methods on which Promega’s accused products are based. The asserted claims were additionally invalid as anticipated or obvious in view of the prior art, including a prior art patent to Caltech, which expired years ago. Judge Posner also found certain claims invalid for obviousness type double patenting. Defendants appealed various aspects of Judge Posner’s decision and the judgment. Six days after oral argument, the Federal Circuit summarily affirmed the judgment, awarding Promega a complete victory in the case.

Represented various women seeking Orders for Protection (OFPs) as a result of abusive relationships. 

Represented mother accused of international child abduction in trial in a federal court trial known as a Hague Convention proceeding. The mother had fled the father in Peru and brought their two minor children to Minnesota. The default in these cases is that the children are returned to their country of habitual residence, and any further proceedings occur there. In this case, the Court found that in light of physical violence toward the mother and others, death threats, and other evidence concerning the children, the children should stay in Minnesota with their mother because returning them to their father in Peru would present a grave risk of physical or psychological harm to the children. 

Represented criminal defendant accused of 12 counts of felony theft by swindle of over $35,000 (alleged mortgage fraud) and 1 count of racketeering. Ultimately agreed to a plea bargain shortly before trial. 

Represented a woman after her life partner became severely brain damaged following a cardiac arrest. Client sought assistance when her partner’s family tried to cut her out of her partner’s life and out of the life of the daughter they had raised together for the past five years. This representation included a one day guardianship trial as well as related family court and harassment matters. At the end of the representation the client could visit her life partner freely and a neutral guardian was appointed. 

Represented the guardian ad litem for three minor children in a termination of parental rights action. Two of the children were conjoined at birth, separated at the Mayo Clinic, and suffered from a number of long-term health issues. When the first was finally released to the parents he suffered severe abuse and injuries including multiple broken bones. The parents and their lawyers and experts argued that the injuries were the result of other congenital defects or disease. After a two-week trial including multiple experts and doctors, radiologists and nurses from the Mayo, as well as other evidence, the court agreed that the parental rights of the parents should be terminated. After the Minnesota Court of Appeals remanded for further findings, and then later affirmed, all three children were adopted by the foster parents who had been caring for them, and are doing well. 

Represented Ski for the Blind in a trademark dispute through MAP for Non-Profits.  

Represented Anti-Child Porn.Org on a confidential matter. Represented clients in housing court through the Volunteer Lawyers Network.
