“I recently engaged Parola Analytics to conduct a prior art search on a difficult US patent that had already stymied another search firm that delivered two unusable references.
Parola found four much better references in two weeks that demonstrated a deeper understanding of the search and an effective selection of the best references.
I highly recommend Parola Analytics.”

“In just weeks, our investments in our relationship with Parola Analytics started to pay handsome dividends. Parola Analytics identified a patent filed by researchers at Yale that showed promise as a vaccine against malaria. Our article, authored by Monisha Ravisetti, was publicized in hundreds of newspapers and magazines worldwide and quoted thousands of times on social media. Parola’s flexibility proved invaluable for a startup company like ours, and the reasonable fee structures allowed us to invest in the relationship with confidence.

The searcher (who is a PhD chemist and registered US Patent Agent) took great care to understand the claim language of a biotech invention prior to doing the search. A very thorough search was done in a timely and efficient manner. I highly recommend Parola Analytics for patentability searches.”
