What role does ‘long-felt need’ play in commercial success arguments for patents?

‘Long-felt need’ is a significant factor in commercial success arguments for patents. It demonstrates that the invention solves a problem that has existed in the industry for an extended period. The MPEP 716.04 states:

Establishing long-felt need requires objective evidence that an art recognized problem existed in the art for a long period of time without solution.

In the context of commercial success:

• It shows that the invention meets a genuine market demand.
• It indicates that the solution was not obvious, as others failed to solve the problem.
• It strengthens the nexus between the invention and its success.
• It can explain rapid market acceptance and growth.

To effectively use ‘long-felt need’ in commercial success arguments:

1. Document the history of the problem in the industry.
2. Provide evidence of previous unsuccessful attempts to solve the issue.
3. Demonstrate how your invention specifically addresses this need.
4. Show how meeting this need contributed to commercial success.

When combined with strong sales or market share data, evidence of fulfilling a long-felt need can be a compelling argument for the non-obviousness of a patent claim.
