About Us

The SUN DO International Patent & Law Office is comprised of professionals equipped with law and science backgrounds and nurtured with specialty training in intellectual property rights. Our specialties cover the fields of patents, trademarks, copyrights, trade secrets, fair trade acts, etc. Having been established for more than two decades and specializing in intellectual property rights, we have devoted our efforts to guiding our customers to optimally deploy their intellectual property, which is the tenet we uphold in regard to benefitting our clients.

You can depend on us to protect your intellectual properties

Many law offices in the market consign intellectual property-related cases to their sales specialists who are underequipped with relevant professional knowledge and skills. Hence, while facing enormous sales pressure, the lack of these specialties will very likely lead to sacrificing the quality of the consigned cases. Worse still, serious defects may occur in regard to the application content as a result of a failure to understand the development focus of a case. In contrast, the intellectual property cases we have undertaken are all directly handled by our professional and experienced engineers.
We are in a very strong position to provide thorough case analysis, detailed and specific patent search and integrated patent deployment for your protection and benefit, as well as offering patent design-around for you to use in your business strategy.

Guardian of intellectual property rights : our strength

With our service team members averaging more than a decade of work experience in the intellectual property field, we have already handled over ten thousand cases in intellectual property rights, and have a monthly output of more than 200 cases. In other words, our solid hands-on experiences are our assurance to help you secure your intellectual brainchild. We have regularly provided our customers with patent technical bulletins in Taiwan (on the 1st, 11th and 21st of each month ), China (every 7 days) and the U.S. (every 7 days), so that you can have your finger on the pulse of the industry and obtain the latest industrial development trends.

For every case undertaken by us, we conduct a thorough search analysis and provide a deployment recommendation (where we offer previous technical information for reference) for you to define the substantive protection range and deployment area as well as to prevent infringement of the patent rights of others. Our on-line case inquiry service will also allow you to get access information regarding the application progress and ensuing procedure of your case at any time.
