"Bill represented my firm in an untrue accusation of copyright infringement. He was quick and compassionate. He included my considerations in his arguments. He followed up with each communication. I really appreciated his client communication with me and his professionalism. I highly endorse Bill!"

"Mr. William is undoubtedly a top notch attorney who has skillfully mastered his primary area of practice over the course of his professional experience. His sharp critical thinking and flawless work ethic are perhaps the key qualities which ensured the success of a remarkable number of his cases. I endorse this lawyer and encourage anyone who needs superior legal representation to opt for his services."

"I've read nearly a hundred of Attorney Lang's responses to Avvo questions. Without exception, his responses are legally sound, insightful, wise and -- most important -- business savvy. I strongly endorse him and would not hesitate to recommend him to anyone seeking intellectual property advice."

"Bill is the consummate patent attorney whom I hold in highest regard for his progress and professional success - which I watched grow first hand. I first met Bill as a law firm associate where I supervised his always meticulous work - because of that attention to detail, he also gets the big picture, and translates those details into meaningful, common sense help for clients. He understands the importance of every step of the legal process as well as how it fits into a client's business; as a further testament to both his character and professional judgment, Bill never lets a detail slide if he feels he does not fully understand its import. Since working with Bill, my legal practice focus evolved to Trademarks exclusively, and so I can without hesitation say that should I need a patent application prepared I would trust Bill with all mine. On a personal note, I always thanked him for introducing me to the enjoyment of shooting skeet. Bill's an all around guy and family man."

"I endorse Attorney Lang. We often post answers to the same legal inquiries on Avvo. Invariably, I agree with Mr. Land's answers. His advice is knowledgable, well thought out, detailed and complete."

"Here’s why I am endorsing Mr. Lang…I’m a relatively new attorney, some of my practice areas overlap with areas where Mr. Lang posts replies to Avvo questions, and every time I read one of his answers I’m impressed, impressed with his legal knowledge, his demeanor, and his word crafting skills. Quite frankly, I’ve learned more from his posts than the many CLE’s I’ve paid for. And I can tell from the quality of his posts, he has no need of my endorsement nor to be taking his time in answering Avvo questions. But he does and I’m thankful for it. And if you’re in need of IP legal services (patent, trademark, copyright, trade secrecy, etc.), Mr. Lang is one of the first places I’d go for a consultation."

"Sometimes one Avvo answer is enough. The answer of Mr. Lang was not only accurate and analytic, it was so customized to the needs of the Avvo asker as to convey considerable value. These are all qualities that every client would look for when hiring an attorney."
