Officers and directors, past 12 months. Their share of stake is being verified and is not shown yet; amounts and trading plans are below.
Officers and directors, Oct 2025 to Oct 2026. Each sale is counted once: under a disclosed plan, else to cover taxes, else no plan disclosed.
| Who | Shares | Price | % of total stake | Total stake after | Trade date | Filed |

| Rajesh Pankaj Chief Technology Officer | 1,500 | $334.32 | n/a | n/a | Oct 5, 2026 | Oct 6, 2026 |
"% of total stake" is the shares in an event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings are not confirmed, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.
Yes. Lawrence Chen sold 30K shares ($9.5M) in the past 12 months, all of it under a trading plan disclosed in the filings.
Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 100% of sales by value ran under 10b5-1 trading plans disclosed in the filings. A trading plan schedules sales in advance.
No. Officers and directors reported no purchases in the past 12 months.

Officer and director open-market sales: $27.2M across 82,692 shares. Plan status and stated purpose are separate questions, and a sale can have both.
$596K of sales (2.2%) cite tax obligations in their footnotes, $596K of them also under a plan. Separately, 86,910 shares ($31.0M) were withheld by the company for taxes, which isn't a market sale. Example: John Markley Jr., Jun 22, 2026
Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.
Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for InterDigital, Inc. are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 1,638 Forms 3, 4 and 5 on record for InterDigital, Inc. (SEC CIK 1405495), filed from Jul 11, 2007 to Oct 6, 2026; 104 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages.
Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.
Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
