Thomas M. Croft

Tom’s practice focuses on all aspects of patents: preparation and prosecution, litigation, USPTO post-grant proceedings, counseling, and due diligence in support of patent-related transactions. In addition to being admitted to the bar in Colorado, he is registered with the USPTO and is admitted to the U.S. District Court for the District of Colorado and the U.S. District Court for the Eastern District of Texas.

Tom is a former electrical engineer with over 20 years of experience with patents—as an inventor, as a patent-support engineer, as a registered U.S. patent agent, and as a patent attorney. Tom has extensive experience in evaluating invention disclosures; both domestic and foreign patent preparation and prosecution; and patent litigation, particularly claim construction, non-infringement analysis, invalidity analysis, and working with technical experts. Tom also has experience with USPTO post-grant procedures such as inter partes reexaminations, Inter Partes Reviews (IPRs), and Post-Grant Reviews (PGRs).

Tom began his college studies majoring in journalism and earned an associate degree in that field before switching to engineering. The writing and interviewing skills he developed while studying journalism and working part-time as a newspaper reporter and radio disc jockey have served him well over the years.

Tom’s engineering education emphasized digital signal processing and communications. He began his career as a Member of the Technical Staff at AT&T Bell Laboratories, where he simulated video compression algorithms, helped to design signal-intelligence systems, and developed signal processing algorithms for cellular telephones. He later joined Ericsson Inc. for ten years, half of that time as an applied research engineer, the other half as a patent-support engineer. While at Ericsson, Tom simulated modulation, channel-coding, and equalization algorithms for cellular handsets. His work at Ericsson led to his becoming a named inventor on ten issued U.S. patents. Tom then worked for four years as a patent agent and, later, as a patent attorney for Hewlett-Packard. At Hewlett-Packard, his work featured the drafting of patent applications directed to digital-camera technology and computer workstations.

Tom then spent ten years at Cooley LLP, a leading general-practice law firm, doing both patent preparation and prosecution and patent litigation before joining Dunlap Bennett & Ludwig PLLC. While at Cooley, he drafted and prosecuted patent applications concerning a wide variety of electrical and mechanical technologies, including anti-malware computer software, social networks, mobile payment systems, video processing and distribution, medical devices, and automobile accessories. Tom also represented clients in patent-litigation matters involving wireless communication, digital printers, on-line learning systems, computer-network security, and object-oriented databases.

During his free time, Tom enjoys playing jazz piano, composing music, reading the classics, watching classic films, and serving in various capacities through his church. He and his spouse have three sons.
