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:

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.

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.

 Trustindex verifies that the original source of the review is Google. I had the privilege of consulting with Patent Attorney James Yang recently, and I must say that my experience was exceptionally positive. Mr. Yang demonstrated a remarkable level of expertise and professionalism throughout our conversation. Although our discussion ultimately led to the conclusion that I wasn't quite prepared to embark on the patent application process, I was deeply grateful for Mr. Yang's guidance and insight. His honesty and thoughtfulness in helping me navigate the complexities of patenting were truly commendable. He patiently walked me through the various stages of the process and provided invaluable clarity on what is required before initiating the patent application. I left our consultation feeling well-informed and with a renewed sense of direction regarding my patent idea. I am genuinely looking forward to working with Mr. Yang when the time is right for me to pursue my patent. His expertise, transparency, and dedication to assisting inventors like myself make him an invaluable resource in the field of patent law. I have no doubt that his guidance will be instrumental in bringing my invention to fruition.

 Verified Navigating the Patent System: Learn the WHYS of the fundamentals and strategies to protect your invention: must-read for inventors Navigating the Patent System is the perfect book for anyone who knows absolutely NOTHING about patents, but has an idea or invention they would like to protect.  After reading Mr. Yang’s book, I am ready to submit a provisional patent!  This book took me from having so many questions and zero confidence, to scheduling appointments with several patent attorneys.  Furthermore, I have a game plan now in place for the patent process.  All of which did not exist before reading this book.  I highly recommend this book for graduates students, post docs, and faculty in academic institutions.  Frankly, I don’t understand why it isn’t offered as a course for grad students.

 Verified Navigating the Patent System: Learn the WHYS of the fundamentals and strategies to protect your invention: A gold mine of patent tips First off, I have patents. I have worked with patent attorneys. I wish Id read this book from start.I will say most people, as the author suggests should hirecan attorney, and read this first. No one UNDERSTANDS your product more than you so read this to better understand the process of protecting your product. I will not begin to explain the points I like about this book, there are too many. I will say, Apter working with an attorney and riding much of my own patent descriptions and claims this book made me rethink many many things in a positive note. This book also made me aware that I had hired a very poor attorney had I read this book 1st I would not have made this mistake because I would have seen it even more clear then I had suspected halfway into my process. I have bought several books on the subject and this is by far my favorite for the simple reasons that he is very clear and concise with his wording and descriptions of certain situations and comparatives patent processes in relation to something you may be doing. Patents ARE confusing, but the author helps to clear up much of what makes it so. The language of describing an invention IS complicated, but he explains it in a way to make it all much easier to wrap your arms around.Regardless of how your filing a patent, buy the book. It is a very small investment into protecting your product / idea.

 Verified Navigating the Patent System: Learn the WHYS of the fundamentals and strategies to protect your invention: This book saved me from Googling myself to death! I came across this book after a few days of exhausting online research trying to learn more about the patent process.  After reading the articles on Mr. Yang's website, I suspected his book would provide the clear and complete explanation that I needed, and I was right!  This book is thorough, well-organized, super helpful and a surprisingly easy read for such a complex issue.  Skip all the Googling and buy this book... I'm sure you'll find it as helpful and informative as I did!

 Verified Navigating the Patent System: Learn the WHYS of the fundamentals and strategies to protect your invention: This is a must read If you are thinking of patenting an invention or inventing something, this is a must read. "Navigating the Patent System" does just that. It clearly goes over everything you need to know to consider whether to patent or not. I first went to a patent lawyer before I read this book and was confused, frustrated, and lost. After reading this book, I felt like I knew what I wanted and how to accomplish it. I was able to talk to the lawyer in a direct and decisive way. This book helped me consider obstacles I never thought of and allowed me to make a wise decision with volition and intention.
