The Value Of Accuracy In The Patent System, Stephen Yelderman Jan 2017

The Value Of Accuracy In The Patent System, Stephen Yelderman

Journal Articles

Because it must rely on imperfect information, the patent system will inevitably make mistakes. To determine how the system ought to err in cases of uncertainty—and whether a given mistake is worth correcting—scholars have composed a simple picture of the consequences of error in either direction. On the one hand, erroneous patent awards impose unjustified costs. On the other hand, erroneous patent denials discourage successful inventors and reduce incentives to create in the future. The result is an essentially indeterminate balancing, in which policies of overly liberal awards drive up costs, and policies of overly cautious awards drive ...

As it turns out, there are a number of ways these conditions can and regularly do fail.

Such a counterintuitive outcome is possible because the Federal Circuit has constructed a highly constrained definition of functionality in design patent law, which is at odds with this Court’s precedent in both utility patent and trade dress cases. Coupled with its recent re-interpretation of the design patent infringement standard, the Federal Circuit’s approach to functionality makes it quite likely that defendants ...
