Who Can OC Patent Lawyer Help?

We work with experienced inventors, first-time inventors, and in-house counsels to pursue and protect the strongest utility patents and design patents in the United States and abroad. Our full menu of patent-law services consists of:

  • Patent Application
  • Patent Defense
  • Patent Enforcement
  • Due Diligence for Mergers & Acquisitions
  • Patent Licensing
  • Patent-Law Consulting for in-House Counsels
  • Worldwide Patent Application & Protection

Our clients are large and small, with varying budgets, and are at various stages of the patent process. Typically we suggest consulting with a patent attorney after you have developed a prototype of your invention, but before you have invested any more money into R&D, marketing, or legal counsel.

We work with inventors throughout Orange County, Los Angeles County, elsewhere in Southern California, and even beyond. All of our work can be done remotely, though most clients enjoy meeting in-person at various stages (and so do we). Many of our clients come from right here in OC, including Irvine, Anaheim, Santa Ana, Costa Mesa, Huntington Beach, Orange, Fullerton, and Garden Grove. Many more come from Los Angeles, Long Beach, Santa Monica, Glendale, Pasadena, Torrance, Lake Elsinore, Murrieta, Temecula, and other nearby communities.

The industries we work in reflect the employers and economy of SoCal. We’ve helped our clients secure patents in industries that include software & apps, electronics, biotech, manufacturing, aviation, automotive, medical devices, optics, tools and equipment, construction, consumer products, food and drink, agriculture, green energy, entertainment, and more.

Why Choose OC Patent Lawyer?

The short answer is because of our:

  • Experience in patent law
  • Focus on patent law
  • Experience in many industries
  • Likely experience in your industry
  • Engineering background
  • Directness as to pros and cons and trade-offs
  • Clarity in explaining complex legal terms and situations
  • Free info (on this site, on YouTube, and in our book)
  • Long track record of helping inventors, as documented in their reviews
  • Laid-back California demeanor (rare in patent attorneys)

Of course, you can determine for yourself whether we’re a good fit (and why) by scheduling a consultation.
