The source you supplied contains only a headline ("InterDigital CEO wooed China – now he's eyeing 6G gains – Light Reading") and a Google News redirect link. There is no article body, no quotes, no figures and no dates to work from.

Your brief prohibits adding information absent from the source and prohibits invented numbers or quotations. Under those strict rules, a 520–1000-word rewrite is not possible: the only verifiable facts available are that InterDigital's chief executive has engaged with China and that the company is positioning for 6G-era licensing revenue. Everything else — deal values, patent counts, licensing timelines, CEO statements — would be fabrication.

Please resupply the item with the full article text (or a working link to the Light Reading story rather than the RSS redirect), and I will produce the rewrite to the exact style, length and JSON format requested.
