TOKYO/GUANGZHOU -- Chinese telecom equipment maker Huawei Technologies, a symbol of high-tech competition between the U.S. and China, had more patent applications than any other global company in 2018. But a closer look at its filings suggests the company still trails American rivals in terms of patent quality.
Only 21% of patents filed by Huawei, which is under strong pressure from the U.S. government, could be classed as highly innovative, according to researchers.
