Strategic advice on resolving interferences

You’ve just received a notice of interference from the U.S. Patent Office. Or maybe you’d like to provoke an interference with another party who is copying your ideas. Your best strategy: Call Patterson. Few Midwestern firms can match our degree of mastery in this complex and nuanced area of patent law.

Interferences are procedures before the Patent Office Board of Appeals to determine priority for awarding a patent when two or more inventors have overlapping claims. It’s an evolving field, and significant changes in the rules and procedures for interference make it essential for inventors to seek the guidance of an experienced and strategic advisor.

Patterson can help you demonstrate the priority of your patent and stake your patent claim – often in far less time than a lengthy litigation, and at a fraction of the expense. Better yet, we can help you anticipate such challenges through a proactive strategy, monitoring competitive patent filings and using the interference process to preempt expensive patent litigation from a competitor’s claim.
