…We Needed A Trademark Lawyer(s) who knew Vietnamese Language and understood Vietnamese Culture…and at the same time who can defend us in court if needed.  There are a few lawyers that meet these criteria.  Rosalind Ong and John Tran took our case as their own and treated us as a family member. “

Our case was about trademarks involving Vietnamese words. We needed a trademark’s lawyer(s) who knew Vietnamese language and understood Vietnamese culture in order to help us with the case and at the same time who can defend us in court if needed.  There are a few lawyers that meet these criteria.  This case was extremely important to us because all of our soup base products are using the word CỐT as part of the brand.  We had spent so much money to brand our trademarks so we cannot afford to lose the case. After meeting John Tran and Rosalind Ong through a friend, we realize that John and Rosalind are the ones that we are looking for. After a thorough research, we asked John and Rosalind to represent our case.

During the preparation process for the case, there were times that we were concern that we may lose the case. However, on the days at the courthouse, I regain my confidence when I saw the trial team of  John, Rosalind, Bill, and Theresa working on the case.  The presentation was very organized, accurate, precise and smooth. All of our expert witnesses, interpreter and confusion witnesses were superb. What really impress me was the way John and Bill cross-examine defendant witnesses. John and Bill stayed with us all the time while waiting for jurors to reach verdict.  I know that Rosalind and John took our case as their own and treat us as a family member. Rosalind was more nervous than us while waiting for verdict and because of it she stayed away from the courthouse. At the end, justice was served and we won the case. Our organization thanks John & Rosalind and their team at Rhema Law for an outstanding performance.  This is truly a teamwork.  – Tuan Nguyen, President & CEO- QUOC VIET FOODS, INC.

He Took the Time to Really Understand my Business

With John Tran I received a more personal approach, in which he took the time to really understand my business and what I was trying to achieve.

Extremely Thorough and Knowledgeable in his Field of Law

John Tran… has provided nothing but the best service. We are a small company and many service related companies make you feel just that way… small. John and his team worked in the complete opposite way. We always felt like a high priority, multi million dollar company based on how he dealt with our business.

John is extremely thorough and knowledgeable in his field of law. He possesses a great skill that many in specialized fields lack… the ability to explain complicated or technical matters in a layman’s terms so you have a very good understanding of what’s going on, what your options are and how things will move forward.

I would not hesitate for a second to recommend John or his firm (and have done so several times) any time their fields of law come into play. Suren Sagadevan, Precision Tees, Inc.
