Ericsson said that Samsung had asked to renew its license for a lesser rate than similar firms pay.
Swedish telecom network equipment maker Ericsson has filed lawsuit against South Korean electronics firm Samsung in the US alleging violation of its patent technology.
Ericsson alleged Samsung is not renewing a license to use its unnamed technology as per the earlier accepted Fair, Reasonable and Non-Discriminatory (FRAND) terms two years ago.
Ericsson said in a statement: "The dispute concerns both Ericsson's patented technology that is essential to several telecommunications and networking standards used by Samsung's products as well as other of Ericsson's patented inventions thatare frequently implemented in wireless and consumer electronics products."
In its fling at the District Court for the Eastern District of Texas in the US, the firm said that Samsung had asked to renew its license for a lesser rate than similar firms pay.
Ericsson has also demanded the US court to bar the sales of various Samsung manufactured products including cameras, Blu-ray Disc players, televisions and phones claiming that they infringe on its patented technologies.
In contrast, Samsung noted that it would challenge the allegations.
Samsung said in a statement that Ericsson demanded higher royalty rates for the same patent portfolio.
"As we cannot accept such extreme demands, we will take all necessary legal measures to protect against Ericsson's excessive claims," South Korean firm said.
