West Chester

For almost 45 years Petock & Petock, LLC has been a trusted source of intellectual property and related business law services for individuals and businesses in the Philadelphia area and nationwide.

Our History

Our firm was founded by the late Michael F. Petock, Esq. in 1972 atop the PSFS building in Philadelphia, the tallest building in Philly at the time. Michael F. Petock was widely regarded as a top patent attorney by his clients, fellow attorneys and judges. The firm relocated to beautiful Phoenixville, PA in the mid 1980’s in an effort to be closer to many of the firm’s clients and the thriving business scene occurring in the Philadelphia suburbs. We have been in Phoenixville ever since and recently have expanded to West Chester in order to provide better convenience to our Chester County, PA clients.

These days the firm’s Managing Partner, Michael C. Petock leads the firm by the principles on which it was founded by his dad almost half a century ago:

  • 1. Know the law.
  • 2. Practice law in a way that earns trust.
  • 3. Be a fierce advocate for your clients.

Why Work With Us

These principle’s have resulted in Petock & Petock being the area’s “go to” IP law firm- the firm even other lawyers look to when they need attorneys they can trust with their own client’s intellectual property matters. Michael C. Petock is proud of the firm’s tradition and reputation and is honored to have been selected by his piers three years in a row as a Main Line Today Top Lawyer in Intellectual Property.

"We work exclusively with Petock & Petock on all matters of intellectual property, from trademarks to patents. Michael has a strong knowledge of trademark law and patent law. He has effectively counseled and helped us register new marks, offered his expert opinion on matters of infringement, and he has aided us in defending our marks both domestically and internationally. We trust Michael and his firm with our complete portfolio of marks and renewals. What’s more, Michael and Joe have helped us file three patent applications and they were invaluable in helping us attain our very first official US patent. When it comes to IP law, I highly recommend consulting Petock & Petock."

"Mr. Petock worked tirelessly to ensure that Camp Abilities: an overnight educational sports camp for children with visual impairments received our trademark for not only our camp name, but for our two motto's "A Loss of Sight, Never a Loss of Vision", & "Believe You Can Achieve". He overcame barriers, ensured us there were no other programs with our name, and pushed me to do the work we needed to do on our end. His dedication, commitment and passion for our program for children with disabilities was very impressive. Michael Petock is a professional, caring, and talented Lawyer with amazing skills and the ability to make this world a better place every day. He helped my camp tremendously!"

Dr. Lauren Lieberman, Founder & Director Camp Abilities, Brockport, NY

"My brother and I recently opened a new winery in California where naming and visual branding is essential.  Surprisingly we found contradictory advice and massive ranges in pricing which made us both hesitant and lacking in confidence regarding whom to hire to assist us with brand protection. Fortunately we found Petock & Petock. Mr. Petock logically and competently walked me through the steps we would be taking, always kept me informed of where we stood throughout the process, and ultimately successfully achieved our goal of protecting our brand."
