“I would like to post my recommendation of Trojan Law Offices and especially Mr. R. Joseph Trojan himself and the members of his team, specifically Adam Diament and Michiko Speier, for their excellent, highly professional, fair and honest services.


Our case concerned filing of a pharmaceutical patent application with the USPTO. We have approached Mr. R. Joseph Trojan because our company was unsatisfied with the services of the law office which initially handled our patent application. Mr. Trojan offered an initial free appointment and consultation. He had demonstrated deep knowledge and friendly attitude that convinced us to hire his services, and we were since not disappointed in our choice. He and his team have handled and navigated the patent application against rough objections from the patent examiner all the way through to the successful allowance not only of the original patent application, but also eventually, to an allowance of an additional patent based on a continuation application of the original patent.


Our company continues, of course, to work with Mr. Trojan in all matters concerning intellectual properties. And we recommend him and his firm highly!”

“Trojan Law Offices has been managing all of the legalities pertaining to my business for almost 2 years, and has been integral and necessary to the growth of my business. I first met with Joseph Trojan in April 2015, after thinking of a brand new product idea that felt was necessary to protect. Joseph Trojan listened to my thoughts, provided discussion and education on the process of obtaining a utility patent, and has made himself as well as his team easily accessible ever since. Since the inception of my invention, I have been working directly with Adam Diament, and feel strongly that his exceptional knowledge of patent law is the reason why my product idea for a portable washing and drying apparatus has become a business that is ready to launch in the upcoming months. With the help of Adam Diament, I was able to secure a utility patent in record time. Adam Diament is extremely responsive to the multiplicity of questions that I ask on a regular basis, and always provides an in-depth explanation so I can understand the legal issues necessary for the growth of my business. I have thus far used the services of Trojan Law Offices to receive my initial utility patent, expand the claims of my utility patent, secure the perfect trademark for my company, and form an LLC. I plan on using the services offered by this firm on an ongoing basis.”
