Patent Warfare

Overview

Definition

Patent Warfare refers to a strategic practice in which a company uses multiple patents that cover varying aspects of the same invention. These patents often have different expiration dates, which allows the original patent holder to prolong control over their invention and prevent competitors from entering the market even after the primary patent expires. This tactic is employed to extend the duration of exclusivity beyond the patent’s standard timeline.

Examples

Pharmaceutical Industry: A pharmaceutical company might secure multiple patents on various components and formulations of the same drug. These could include the active ingredient, the method of synthesis, the specific dosing regimen, and even secondary uses of the drug, thereby extending their market control well beyond the initial patent expiration.
Technology Sector: A tech company might patent different elements of a single device, such as the software, user interface, hardware components, and connectivity methods. Each patent can have a different expiration date, ensuring prolonged market dominance.

Frequently Asked Questions

What is the main goal of Patent Warfare?

The main goal of patent warfare is to prevent competitors from entering the market by extending the duration of patent protection through related patents on slightly different aspects of the same invention.

How does Patent Warfare affect innovation?

While patent warfare can protect a company’s innovations and provide extended market control, it can also stifle competition and hinder new innovations by making it difficult for other companies to enter the market with competing or improved products.

Is Patent Warfare legal?

Yes, patent warfare is legal as long as the patents in question are valid and granted by the relevant patent office. However, the practice is sometimes critiqued as being anti-competitive.

How does Patent Warfare impact consumers?

For consumers, patent warfare can lead to prolonged periods of high prices and limited access to generic or alternative products, as competitors are unable to enter the market and drive prices down.

Can smaller companies use Patent Warfare?

Smaller companies typically find it more challenging to engage in patent warfare due to the high costs and resources required to obtain and maintain multiple patents.

Patent Thicket

A dense web of overlapping patents a company creates, making it difficult for others to innovate without infringing on existing patents.

Evergreening

A tactic where patent holders obtain additional patents on slight modifications of the original invention, effectively extending the patent’s overall lifespan.

Patent Troll

An individual or company that acquires patents not with the intention to develop or market the invention but to profit from any infringement claims.

Blocking Patents

Patents intended to block competitors from developing similar inventions, even if they do not plan to commercialize the patented technology themselves.
