Meaning
Specific descriptions of an invention that lack a signed transfer document constitute a gap in a company’s patent portfolio. The existence of unassigned patent claims means that the original inventor still holds the rights to those parts of the application. If an individual leaves the firm without signing a broad assignment, that person might retain the power to license the technology to others.
Legal Fragmentation
Control over a patent is determined by who owns each of the individual statements that define the invention’s scope. When some unassigned patent claims exist, the company cannot claim exclusive ownership of the entire patent. This situation allows the inventor to practice the invention or license those specific parts to competitors.
Rectification Effort
Procurement of a supplemental assignment is the standard way to fix this issue after it is discovered. The company must convince the inventor to sign a document that specifically mentions the omitted claims or covers all related inventions. If the relationship with the inventor has soured, this can become a costly and difficult negotiation.
Claim Audit
Investors carefully check the chain of title for every claim in a patent to ensure there are no surprises. A single missing signature on an assignment form can jeopardize the value of an entire patent family.
