Unique History

In 1991, Roberto Ronquillo, a Civil Engineering graduate from the Philippine’s premiere state university had an idea for a unique product that he wanted to be protected thru a patent. With no experience then in Intellectual Property matters, he tried to seek assistance from several local law firms in the drafting and filing of his very first invention but was dismayed at the difficulty in communicating his idea as well as the prohibitive fees charged then. Frustrated, he decided to totally forgo the services of a patent agent and proceeded to draft his own patent application guided only by his research in the Philippine Patent Office. Without the aid of any patent attorney, Engineer Ronquillo managed to file his very first patent application in August 1991 and in less than a year’s time (1992), he was able to obtain a patent for his invention. This experience became the start of honing his expertise in filing the various intellectual property requirements for his family business for the next 10 years.

Often besieged by inquiries from friends (and sometimes, strangers) on how to go about in filing trademarks and patents, Engineer Ronquillo realized that there was a tremendous need for the services of an Intellectual property consultant in the Philippines, one who could provide a personal approach to the practice, guiding clients in all phases from concept to conclusion. Supported by his lawyer friends, Patentprose was formally established in 2001, initially with the simple mission of assisting fellow Filipinos in the filing and maintenance of their inventions and trademarks with the IPO. However, shortly after setting up the company, inquiries from associates all over the world started to come in and the rest is history. In 2007, Engineer Ronquillo joined the elite group of registered Philippine patent agents by passing the very first Patent Agent Qualifying Exam (PAQE) offered by the IPO Philippines.

Today, from its humble beginnings in 2001, Patentprose has built longstanding and firm relationships with clients worldwide and these have survived the test of time because of the quality and consistency of service that it provides to all of its clients.

Core Team

Engr. Roberto Ronquillo

Engr. Roberto Ronquillo
Managing Director
Registered Patent & Trademark Agent

Engr. Roberto Ronquillo’s extensive background as an inventor, patent and trademark agent, engineer and entrepreneur enables him to bring a unique combination of technical, creative and business experience to Patentprose.

He is a Bachelor of Science in Civil Engineering graduate from the country’s premiere state university, University of the Philippines, Diliman, Quezon City. In 2007, he officially became a Registered Philippine Patent Agent, after successfully hurdling the very first Patent Agent Qualifying Exam (PAQE) offered by the IPO Philippines. In 2012 he was awarded as one of the “100 Outstanding Engineers of the Century”, a prestigious award given by his alma mater, the University of the Philippines.

Experience as an Engineer and Entrepreneur
In 1985, immediately after graduation from college, he had his first taste of becoming an entrepreneur when he established his own company engaged in the installation of communication antenna systems in the Philippines.

In 1987, in his desire to avoid the substantial costs of buying a brand new utility vehicle for his growing antenna installation business, he attempted to build his own utility vehicle thru self-study and using mostly surplus parts. The unexpected success of his first attempt encouraged him to establish a company engaged in the manufacture of low-cost AUV (Asian Utility Vehicles) and CBUs (completely built-up units) in 1988. In 1991, while on a road trip on a hot, sunny day, he suddenly hatched an idea for a product that would help reduce the heat inside a vehicle by improving the efficiency of the air-conditioning system. The product was a revolutionary multi-layered dashboard cover with UV inhibitors (commercially called “Dashield”) which became a huge commercial success among Philippine car owners. In 1992 he established the current family business engaged in the manufacture and distribution of locally manufactured accessories for automobiles (dashboard covers, bull-bars, bodykits, side skirts, claddings, cargo trays etc.). All accessories were designed by Engr Roberto himself and are each protected by patents.

Experience as an Inventor and Patent Agent
Engr Roberto officially became an inventor in 1992, when his own idea (a multi-layered dashboard cover with UV inhibitors) was granted a patent in 1992. Without the help of any patent agent and armed only with his desire to have his idea protected thru a patent, he managed to draft his own patent application thru his research at the Bureau of Patents (now IPOPHL) library. After receiving his first Philippine patent in 1992 and the commercial success of his first invention, he continued to develop and design more products mostly related to the automotive industry. In 2002, a petty theft of his vehicle’s side mirrors encouraged him to develop an automobile side mirror guard which he filed as an invention and was eventually granted registration. His creativity and ingenuity as an inventor was not confined to a single industry however. In 2001, driven by the need to have an efficient cleaning system for the gallon bottles of his water refilling business, he invented a unique mechanical bottle scrubber device which was eventually granted a Philippine Patent. In 2012, an ankle injury that left him temporarily disabled led him to the idea of inventing a device designed to aid persons with foot and ankle injuries. In 2018, during the construction of a new office building, he developed an idea for a long span aluminum louver assembly for which a patent application is currently pending.

Engr Roberto formally established Patentprose in 2001, realizing that there was a tremendous need for the services of an Intellectual property consultant in the Philippines and that he himself already had ample knowledge then in the filing and prosecution of trademark and patent applications as well as in dealing with the IPOPHL. He became a certified Philippine Patent agent in 2007.

As an inventor, he has filed no less than 65 patents in his name to-date (inventions, industrial designs and utility models combined) – arguably, a remarkable feat that no other registered patent agent in the Philippines can boast of. Such a vast experience no doubt brings creativity to the patenting process whenever necessary.
