Intellectual Property Litigation

When your intellectual property assets are under attack — the patents, copyrights, trademarks and trade secrets at the core of your business — choose experienced trial lawyers who believe in your ideas and understand the complexities of your innovations.

Armstrong Teasdale’s intellectual property litigation practice group consists of trial attorneys with a proven track record in this unique area that combines evolving scientific technologies with law.

Using a team approach, our trial attorneys join forces with our patent lawyers and other intellectual property specialists, who have degrees in chemistry and biochemistry, biological sciences, electrical and mechanical engineering, information systems and other technical fields.

We also urge our clients to become members of this team. When they take an active role, it improves communications and helps us do a better job.

We’ve found that this team approach is the most thorough and efficient way to analyze the often changing strengths and weaknesses of each case. The best results in intellectual property disputes come when the opposition understands that litigators are fully prepared to try the case to verdict.

Although most cases are resolved before trial, having a well-prepared team is an important factor in obtaining the best settlement. We pride ourselves not only in the cases that we have tried to verdict, but also in those matters that ended before trial, either though settlement, licensing, summary judgment or dismissal.
