Intellectual Property Law

Solving sophisticated intellectual property matters for your business.

Over 50 years of combined intellectual property legal experience.

Lapple Ubell IP Law is a boutique intellectual-property law firm located in Irvine, California. Our focus and passion is the protection of the intellectual property that drives the fortunes of some of the biggest — and smallest — companies in Southern California.

We help inventors and entrepreneurs guard their essential business ideas and products — and enforce the legal rights in these assets — against infringers, counterfeiters, and overreaching competitors.

Founded by USPTO-registered patent attorneys, Matthew C. Lapple and Franklin D. Ubell, each of Lapple Ubell’s attorneys has extensive experience representing Fortune 100 companies at national law firms. Our attorneys combined have over 50 years of experience working in the intellectual property field. But Frank and Matt founded their own firm to provide a more diverse clientele with the same legal expertise and attention to detail that large-law-firm clients have come to expect … with the personal attention and continuity of service that bigger firms cannot afford to provide.
