Invalidity and Validity Search Services

A government-issued patent certificate looks incredibly official, but it is not an unbreakable legal shield. Patent examiners are human; they review thousands of applications and sometimes miss older inventions hidden in foreign databases or obscure academic journals. Because of this, a patent can be legally challenged and destroyed even after it has been formally granted.

Whether you are trying to break a competitor's patent that is threatening your business, or you need to double-check the strength of your own patent before demanding royalties, you need a highly targeted investigation. This high-stakes process is known as an Invalidity or Validity Search.

While they use the exact same research techniques, they are used for two completely opposite business goals.

Invalidity Search: Breaking a Competitor's Patent

If your company receives a cease-and-desist letter accusing you of patent infringement, or if a competitor's patent is unfairly blocking your path to market, an Invalidity Search is your best legal defense.

The goal here is aggressive: we want to find the definitive prior art disclosure that the government examiner missed. We hunt for older patents, foreign products, or forgotten research papers (prior art) that prove the competitor's invention was not actually new when they filed it. If we find this evidence, we can use it to legally invalidate their claims through a formalopposition or revocation proceeding, completely removing the legal threat against your business.

Validity Search: Proving Your Patent's Strength

On the flip side, a Validity Search is a defensive maneuver. If you own a patent and are preparing to sue someone for copying your product, the very first thing the defendant will do is try to invalidate your patent.

Before you spend millions of rupees taking them to court, you must ensure your patent can survive the attack. A Validity Search acts as a stress test for your own intellectual property. We aggressively search your patent just like a competitor would. If your patent survives our search, you can confidently proceed with litigation or confidently negotiate high-value patent licensing deals knowing your asset is legally bulletproof.

How This Differs from a Standard Prior Art Search

You might be wondering how this is different from a standard prior art search.

A standard search is done before you file, casting a wide net to see if your general idea is patentable. An Invalidity/Validity Search is done after a patent is granted, and it is forensically precise. Instead of looking at a broad concept, we dissect the specific, legal "Claims" written at the very end of the target patent. Our patent attorney near you analyzes every single word and limitation, utilizing advanced structure-based searches, Locarno classifications, and local language translations to find the exact piece of historical evidence that breaks that specific claim.
