Patent Law
The lawyers I have worked with from SeedIP law firm over the past 20 years understand the patent law very well. They always provide us the precise guidance and advice through the IP jungles. They also do a very detailed prior art analysis and advise us on what can be claimed based on our discoveries and what has been out there.
Zaihui Zhang, Senior Director – Signalchem Lifescience Corp.
Biotechnology and Life Sciences Practice
I have been using SeedIP for our patent portfolio management for 20 years even though I have changed jobs several times. I always recommended SeedIP law firm to the companies I have worked and to other local biotech companies who are in need of external IP management. The lawyers I have worked with are very knowledgeable, resourceful, professional, easy to communicate with, and very helpful in guiding us to develop strategies to protect our IP space. The cost is very reasonable as well which is a big plus for small biotech companies like us. The patent applications drafted by their lawyers in the areas of small molecules and biologicals are top quality. I really appreciate their professional advice and efforts in protecting our intellectual property.
Zaihui Zhang, Senior Director – Signalchem Lifescience Corp.
