Obituary for Larry Maxham: A respected colleague, mentor, and friend to the SDIPLA


With a heavy heart, we announce the passing of Lawrence “Larry” A. Maxham, a beloved father, devoted husband, cherished friend, and esteemed colleague. A true renaissance man, Larry’s passion for life was matched only by his dedication to the field of intellectual property law.

As an avid golfer and patent attorney extraordinaire, Larry’s presence graced the corridors of the San Diego Patent Law Association long before its transformation into the San Diego Intellectual Property Law Association. Throughout his illustrious career, Larry’s practice showcased remarkable diversity, with a significant focus on preparing patent and trademark applications that offered his clients unparalleled legal protection on a global scale.

Larry’s expansive network of contacts with Intellectual Property attorneys worldwide allowed him to secure the highest legal representation for his clients in their international pursuits. He took great pleasure in meeting with foreign attorneys, ensuring they were best suited to handle his clients’ specific needs and fostering meaningful relationships across borders.

For many of us, Larry was not just a colleague but also a dear friend and a mentor. When we entered the legal profession, he showered us with his generous guidance and unwavering support, always willing to impart his vast knowledge and experience. The impact of his absence will be deeply felt, not only by those of us fortunate enough to have known him closely but also by the countless lives he touched throughout his remarkable journey.

In commemorating Larry’s life, let us celebrate the extraordinary person he was – a beacon of warmth, kindness, and professionalism. The legacy of Lawrence “Larry” A. Maxham will forever resonate in our hearts and within the fabric of the SDIPLA community.

The memorial service is Sunday at 1 PM at El Camino Memorial Park
