Provisional applications tempt stakeholders with the possibility of securing a filing date on an expedited basis and limited budget, but the value of that filing date will depend on its ability to serve as a valid priority date for the invention claimed in the non-provisional application. The non-precedential Federal Circuit decision in Purdue Pharma L.. v. Iancu shows that even a robust provisional application may not suffice if it does not include “blaze marks” that point out the claimed invention with “adequate specificity.”

The Patent At Issue

A business decides to file a trademark. Someone on the team searches for a familiar online legal-services brand, clicks the first result, and lands on a site with a similar-sounding name, a polished design, five-star reviews, and a low flat fee.
