The Strategic Advantage

Why Technical Expert Testimony Is Decisive

Patent litigation often lives and dies on technical credibility. Judges and juries are rarely experts in the technology at issue and therefore rely on expert witnesses to translate complex engineering concepts into clear, legally relevant conclusions. A weak or unconvincing expert can unravel an otherwise strong case.

Our firm brings a rare combination of legal and technical training. With a Master of Engineering in Electrical Engineering, a J.D., years as a practicing USPTO patent examiner, and lead-counsel experience in federal patent litigation, we are equipped to provide testimony grounded in both engineering fundamentals and real-world courtroom practice — giving your case a credible, court-ready voice that holds up under cross-examination.

Inside the USPTO

Former patent examiner in control systems, power electronics, and AI — providing unique insight into examination standards and prosecution history.

Lead Litigation Counsel

Has argued in multiple patent ligiation cases, managed discovery, and litigated against various S&P 100 companies as lead counsel.

Reliable Under Cross

Testimony built on defensible methodology, engineering depth, and legal precision — designed to withstand vigorous cross-examination.

Responsive & Available

Timely turnaround on reports and declarations to meet discovery deadlines and briefing schedules.

Areas of Expert Testimony

Comprehensive technical analysis and court-ready testimony across the full spectrum of patent and technology disputes.

Patent Claim Interpretation & Construction

The scope of a patent claim is typically the foundation of every infringement or validity dispute. Expert claim interpretation provides courts with the evidence needed to rule at Markman hearings or dispositive motions.

  • Construction of disputed claim terms for Markman hearings
  • Analysis of prosecution history and file wrapper estoppel
  • Claim scope analysis under plain meaning vs. specification
  • Declarations and briefs in support of claim construction positions

Expert Infringement Analysis

A rigorous, element-by-element comparison of the asserted claims against the accused product or process is essential to establish — or defeat — a claim of infringement, including analysis under the doctrine of equivalents.

  • Literal infringement and doctrine of equivalents analysis
  • Technical review and teardown of accused products and systems
  • Source code, firmware, and schematic review
  • Preparation of infringement and non-infringement expert reports

Electrical & Computer Technology Testimony

From semiconductor circuits to networked software systems, expert testimony in electrical and computer technology requires both engineering depth and legal clarity. With an M.Eng. in Electrical Engineering and years of hands-on practice, Mr. Cummins provides credible, understandable testimony on highly complex subjects.

  • Digital circuits, power electronics, and embedded systems
  • IoT devices, smart assistants, and SoC architectures
  • Industrial control systems and automation technology
  • Consumer and commercial electronics

Patent Validity & Invalidity Analysis

Challenging patent validity requires a thorough prior art search and rigorous technical analysis of anticipation and obviousness. Expert opinions are essential to IPR petitions, inter partes review, and invalidity defenses in district court litigation.

  • Prior art identification and claim mapping
  • Anticipation and obviousness analysis under §§ 102 & 103
  • IPR and PTAB proceeding support
  • Written description and enablement challenges under § 112

USPTO Practice & Patent Prosecution Standards

As a former USPTO patent examiner, Mr. Cummins has firsthand knowledge of examination standards, office action practice, and the inner workings of the USPTO. This expertise is invaluable in cases involving prosecution history, inequitable conduct, or patent office procedure.

  • USPTO examination standards and procedures
  • Office action and interview practice analysis
  • Inequitable conduct and prosecution laches issues
  • Patent drafting standards and claim strategy evaluation

Expert Reports & Declarations

A well-crafted expert report is a powerful advocacy tool. Mr. Cummins prepares opening, rebuttal, and reply reports in compliance with Rule 26(a)(2), clearly communicating complex technical positions to both the court and opposing counsel.

  • Rule 26(a)(2) compliant opening expert reports
  • Rebuttal reports responding to opposing expert positions
  • Declarations in support of motions and Markman briefing
  • Deposition preparation and trial testimony support
