OpenTable, Inc. — commonly "OpenTable" — is an online restaurant-reservation company founded July 2, 1998 (originally incorporated in California as easyeats.com, Inc.) and headquartered in San Francisco, California. It was publicly traded on Nasdaq under the ticker OPEN until Booking Holdings, Inc. (NASDAQ: BKNG) acquired it in an all-cash deal for $2.6 billion in 2014; it has operated as a wholly owned Booking Holdings subsidiary since. Employee counts vary by source (Wikipedia cites 1,450 for 2019; third-party data aggregators give bands of roughly 1,000–5,000). As a subsidiary, OpenTable no longer reports standalone revenue; its last disclosed figures as a public company were about $190 million in 2013.
Products and operations. OpenTable operates a two-sided restaurant reservation marketplace and software suite. For diners, it offers web and mobile apps for discovering restaurants, reading reviews, and booking tables. For restaurants, it sells reservation and table-management software (an electronic reservation book), guest-management and CRM tools, marketing and analytics products, and integrations with point-of-sale systems and third-party platforms. It is an operating company with real products and services, not a non-practicing entity.
Litigation posture. The tracked data shows one case, in which OpenTable is a defendant (0 as plaintiff, 1 as defendant), consistent with an operating company being targeted rather than an active enforcer. The case — InternetAd Systems, LLC v. Opodo Limited et al. — was filed in the U.S. District Court for the Northern District of Texas, Dallas Division. InternetAd is a licensing subsidiary of Acacia Research Corporation, and the court record in that matter describes it as a non-practicing entity asserting patents (U.S. 5,572,648 and related) originally owned by inventor David Judson covering internet advertising/reservation-linked technology.
Context. Public records also show OpenTable defending hospitality-reservation patent suits brought by Ameranth Wireless around 2011–2012 involving mobile and web reservation systems; those actions are not part of the tracked case list here. The tracked venue is the N.D. Tex. Dallas Division, not the Eastern District of Texas often associated with NPE filings.
