(Bloomberg) -- Reddit Inc., the social media platform gearing up for an initial public offering this week, said Nokia Oyj has accused it of infringing some of their patents. 

Nokia Technologies, the company’s licensing business, sent Reddit a letter on Monday with the claims, and Reddit is evaluating them, according to a filing made Tuesday. “As we face increasing competition and become increasingly high profile, the possibility of receiving more intellectual property claims against us grows,” Reddit said in the filing. 

Nokia’s claims come as Reddit prepares for an initial public offering in an effort to raise hundreds of millions of dollars. The company has been working toward a listing for years, and its public market debut this week is set to become a high-profile addition to the year’s roster of newly and soon-to-be public companies.

Nokia is no stranger to patent fights. In February, the company reached a patent agreement with Chinese phone maker Vivo, ending a years-long dispute that dragged the two companies into court and forced Vivo to pull out of Germany. In 2021, Daimler and Nokia settled a dispute over the licensing of wireless technology patents in cars, ending a legal battle that had at one point threatened sales of the iconic Mercedes brand in its home country.
