Bibliographically coupled patents: Their temporal pattern and combined relevance

作者：

Highlights：

• A temporal pattern exists for bibliographically coupled patents of an expanding field.

• Conventional BCS measures may be biased against aged and long-spanned BC pairs.

• A simple measure, combined relevance (CR), is proposed to counter such impact.

• A fixed CR threshold may be more safely applied with a reduced possibility of erroneous removal.
