Dutch type foundry Typotheque has filed a lawsuit against the people behind Rick Santorum‘s presidential campaign website, claiming that the site allegedly uses the Fedra font without permission.

The website in question was developed for the Santorum campaign by a Virginia-based consulting company. Neither Rick Santorum nor the America’s Foundation PAC are named in the suit being brought by Typotheque, but the dispute could nevertheless prove embarrassing for the candidate.

Font copyright is a growing issue in the online world, with many people unaware that some fonts are copyrighted by their creators. Permission to use certain fonts can cost more than £100 a pop, even up to £1,000 for some fonts. In other words, this is big business.

Just last month, NBC Universal was sued by the P22 Type Foundry company for allegedly using the Cezanne Regular font on Harry Potter theme park merchandise without permission.
