Best 10 Patent Invalidation Strategies and Tools

Successfully invalidating a competitor’s patent is a powerful maneuver that extends far beyond simply winning a legal dispute. Patent invalidation provides immediate freedom to operate, allowing a company to develop and sell products without the threat of costly infringement litigation or licensing demands. More than just a defensive shield, patent invalidation serves as an offensive tool that can dismantle a rival’s market monopoly, level the competitive playing field, and neutralize threats from patent assertion entities.

Benefits

Invalidating a competitor’s patent provides significant defensive and offensive advantages that directly impact a company’s ability to compete.

Successfully nullifying a patent can also serve as a powerful offensive maneuver, clearing the market of a competitor’s monopolistic barrier and opening it up for the company and others to innovate and compete on a level playing field. This not only saves the company from potential licensing fees but can also disrupt the business model of patent-holding entities (trolls) that rely on licensing weak or overly broad patents for revenue.

Beyond the immediate legal and competitive relief, invalidating another’s patent yields substantial long-term strategic and financial rewards. It enhances a company’s reputation and establishes it as a formidable player in its industry, capable of defending its technological space. This can deter future frivolous infringement claims. Financially, removing a blocking patent can significantly de-risk a company’s operations, making it more attractive to investors and potentially increasing its market valuation.

Patent Invalidation Strategies

Substantive Grounds for Invalidation

Challenges on substantive grounds attack the fundamental merit and legitimacy of the claimed invention’s right to a patent monopoly. These can be because of:

Prior art (anticipation or lack of novelty): this is one of the most common strategies and involves finding evidence that the invention was already known to the public before the patent’s filing date. This evidence, known as “prior art,” can be in the form of earlier patents, published articles, or any public disclosure that describes the invention. If a single piece of prior art discloses every element of the claimed invention, the patent can be invalidated for lacking novelty.

This is very frequent as the information could be:

• the company grounded its R&D on on university thesis or research, or their employees brought their ideas …
• the company searched for investors
• the company did some market research to evaluate the potential of the innovation …
• beta tests ….

Obviousness (lack of inventive step): even if an invention is new, it may not be patentable if it is considered obvious to a person with ordinary skill in the relevant field. This strategy involves demonstrating that the invention is a predictable combination of known elements from multiple prior art sources.

Insufficient disclosure (lack of enablement and written description): a patent must provide a detailed and clear description of the invention so that a person skilled in the art can replicate and use it without undue experimentation. If the patent fails to provide this level of detail, it can be invalidated for lack of enablement or an inadequate written description.

Non-patentable subject matter: patent laws in most jurisdictions exclude certain categories from patentability, such as abstract ideas, laws of nature, and natural phenomena. This strategy argues that the patent’s subject matter falls into one of these excluded categories.

Prior public use or sale: with some commonalities with prior art (the invention was already known to the public before the patent’s filing date), a patent can be invalidated if the invention was communicated, in public use or offered for sale before the patent application was filed (subject to grace periods in some countries like the U.S.). This strategy requires providing evidence of such public use or commercial activity that predates the critical date of the patent filing.

• A public use involves using the invention in its natural and intended way in a public setting, even if the inner workings are not fully understood by the observers. For example, demonstrating a new type of drone at a public park.
• An on-sale bar is triggered when the invention is offered...
