MASUVALLEY & PARTNERS is an Intellectual Property Law firm focusing on international patent prosecution. Our attorneys have strong backgrounds in the Biotech, Medical, Life Science, and Semiconductor fields. Our support is strategic, practical, and is tailored to meet our clients’ overall business objectives.

Masuvalley & Partners is an international IP firm with offices in Tokyo, San Diego, Shanghai, and Bangkok. We provide specialized search, validity analysis, and prosecution services in all areas of IP law, including patents, trademarks, designs, and copyrights.

Masuvalley & Partners was established in 2004 in San Diego, California. Over the last nine years, we have expanded into Asia, opening offices in three countries and building relationships in four others. Since we are an international firm, communication is very important. Our attorneys speak their native language and English, so we are able to provide clear explanations and prompt responses. By having a physical presence in Asia, we are also able to provide our clients with high quality work at a fraction of the price when compared to the larger foreign filing IP firms.

How can we do this? By having already established a presence in Asia, we eliminate the duplication of work and reduce the expenses frequently incurred when filing in foreign countries. We pass the savings along to the client by offering Set Package Prices for all intellectual property matters, thus eliminating any uncertainty related to attorney’s fees, filing fees, government fees, etc. You will know in advance what it is going to cost you - no surprises! Masuvalley & Partners guarantees efficient and timely service to your satisfaction.
