The overlooked citations: Investigating the impact of ignoring citations to published patent applications
作者：
Highlights：
• A patent application may result in a published patent application (PPA) and a granted patent.
• A patent’s PPA individually and concurrently receive citations after the patent is granted.
• Ignoring citations to the PPAs may lead to significant undervaluation to the patents.
• The depreciation is worse when patents and their published applications have longer gaps.
• Main paths derived from networks with and without citations to PPAs are very different.
