InterDigital, the patent collector and licensor, said yesterday that it has ended all litigation with Huawei and  licensed its patents to the company.

The licence is for three years and covers wireless technology patents.

The two companies have been suing eachother for 15 months with Huawei alleging unfair licensing terms and InterDigital alleging breach of patents.

The deal is thought to be worth about $40 million a year to InterDigital which last year had revenues of $318 million.
