Chinese telecom giant Huawei on Tuesday denied allegations by a Portuguese inventor that it had stolen his intellectual property (IP).

The denial was in response to a Wall Street Journal report last Friday that said the U.S. government was investigating Huawei for alleged theft of smartphone camera patents. Patent owner Rui Pedro Oliveira said that after a 2014 meeting with Huawei to discuss his camera designs, the company did not agree to use his IP, but later started to sell products that infringed upon it.

In a statement Huawei issued Tuesday, the company admitted its representatives did meet with Oliveira, but asserted the smartphone cameras involved were developed by staff “having no access to Oliveira’s information,” state-run China Daily reported. Huawei said its products, with nonexpandable lenses and lenses on both sides designed for panoramic photos, are different from the inventor’s single-lens designs, China Daily said.

Huawei also said Oliveira is “taking advantage of the current geopolitical situation” as well as “pushing a false narrative through the media in an attempt to capitalize on a dispute,” according to China Daily.

Huawei has yet to respond to Caixin’s requests for further comments.

The company has denied several IP infringement accusations, and is gradually shifting towards 5G and semiconductors in China as overseas business is impeded by foreign security concerns and U.S. sanctions. Huawei’s own computing ecosystem Kunpeng has bases in China’s five emerging high-tech areas: Shenzhen, Chongqing, Xiamen, Shanghai and Chengdu.
