Texas Patent Litigation

A patent lawsuit can place critical products, revenue, and business relationships at risk. Whether enforcing patent rights or defending against infringement allegations, businesses need counsel who can understand the technology, develop the evidence, and navigate the court’s procedures with a clear litigation strategy.

Perilla Knox & Hildebrandt represents patent owners and accused infringers in Texas patent litigation, including cases before the U.S. District Courts for the Eastern and Western Districts of Texas. We serve companies based in Texas and businesses across the United States and internationally whose patent disputes bring them before Texas courts.

Our attorneys combine litigation experience, technical backgrounds, and patent prosecution knowledge to address the issues that shape a patent case: claim construction, infringement, validity, enforceability, and damages. From initial investigation through trial and appeal, we focus on the client’s commercial objectives and the evidence needed to advance them.

Eastern District of Texas Patent Litigation

Early preparation. Precise contentions. A case built on evidence.

Patent litigation in the Eastern District of Texas requires careful attention to the court’s Local Patent Rules, the assigned judge’s procedures, and the scheduling orders entered in the case. The court’s patent rules address infringement and invalidity contentions, supporting document production, and the sequence of claim construction proceedings.

Those requirements make early investigation essential. For patent owners, we analyze the asserted claims and accused products to develop infringement positions supported by technical evidence. For accused infringers, we examine the allegations, investigate how the accused technology operates, and evaluate prior art and potential invalidity defenses.

We approach contentions as the foundation for the case. The positions developed at this stage inform discovery, expert analysis, claim construction, and the arguments available as the litigation progresses.

Claim construction and technical case development.

The interpretation of disputed claim terms can determine which infringement and validity arguments remain viable. We develop claim construction positions grounded in the patent’s language, specification, prosecution history, and relevant technical evidence.

Our attorneys work with inventors, engineers, company personnel, and experts to connect those interpretations to the accused technology and the prior art. We use that work to guide discovery and prepare clear explanations of the technical issues for the court.

Throughout an Eastern District case, we assess opportunities to narrow the dispute, pursue dispositive motions, negotiate a resolution, or prepare the remaining issues for trial.

Western District of Texas Patent Litigation

Strategy tailored to the assigned court and case schedule.

Patent litigation in the Western District of Texas requires attention to the assigned judge’s standing orders, applicable local rules, and case-specific procedures. Patent case schedules and requirements can vary, making it important to evaluate the governing orders at the outset.

We develop litigation plans that account for the sequence of contentions, claim construction, discovery, expert proceedings, and trial preparation. Our early analysis identifies the technical evidence, witnesses, prior art, and business records needed to support the client’s positions within that schedule.

For patent owners, we focus on establishing a coherent infringement case and anticipating challenges to the asserted claims. For accused infringers, we evaluate noninfringement, invalidity, and other available defenses while assessing potential exposure and opportunities for resolution.

Venue, transfer, and coordinated proceedings.

Where a patent case proceeds can affect litigation costs, access to witnesses and evidence, and the demands placed on the client’s business. We evaluate venue and potential transfer issues early, including the relevant facts concerning the parties, accused activities, business locations, and sources of proof.

We also consider how related litigation and proceedings before the Patent Trial and Appeal Board (PTAB) may affect the Western District case. That analysis includes potential stays, overlapping issues, procedural deadlines, and the consequences of arguments advanced in different forums.

Our objective is a strategy that accounts for the entire dispute and adapts as the court’s rulings and the factual record develop.

Technical Understanding. Commercial Judgment.

Patent disputes often require counsel to move between detailed technical analysis and decisions with significant business consequences.

Our technical experience includes software and computer systems, artificial intelligence, telecommunications, electronics, semiconductors, mechanical and electromechanical systems, and consumer products. We examine source code, product documentation, engineering records, testing, and other evidence to understand how the technology works and where the parties’ positions differ.

We pair that analysis with an assessment of the client’s priorities. Protecting a core product, preserving market access, supporting a licensing program, or resolving uncertainty may call for different approaches. We help clients weigh those objectives against the strength of the case, potential remedies, litigation costs, and the practical value of a negotiated outcome.
