BACKGROUND According to its Amended Complaint, ZoomInfo is a Delaware limited liability company with a principal place of business in Vancouver, Washington, offers a living view of a company’s Total Addressable Market, and enables teams

to prioritize high-value accounts, access real-time insights, and automate strategic outreach. Am. Compl. at ¶¶ 3, 10. ZoomInfo states that its agent-ready data ecosystem is designed to power both internal and external AI solutions, ensuring

that businesses can act on timely, relevant insights. Id. at ¶ 4. In addition, ZoomInfo contends that its contributions to the field of go-to-market technology are protected with a patent portfolio, including the Asserted Patents. Id. at ¶ 5.

The Amended Complaint states that ZoomInfo is the owner by assignment of all right, title, and interest in the Asserted Patents. Id. at ¶¶ 34–35. The Asserted Patents share a common specification and claim priority to the same

provisional application, U.S. Patent Number 62/114,068, titled “Predictive Analytics for Leads Generation and Scoring.” ’609 Patent at 1:8–11; ’964 Patent at 1:8–16. The ’964 Patent is a continuation of the ’609 Patent. ’964 Patent at [63]. The ’609 Patent was issued by the United States Patent and Trademark

Office (“USPTO”) on August 13, 2019, and the ’964 Patent was issued by the USPTO on July 29, 2022. ’609 Patent at [45]; ’964 Patent at [45]. The ’609 patent is titled “Web Crawling for Use in Providing Leads Generation and Engagement

Recommendations” and is directed to an automated predictive analytics system providing for generating sales leads with lead engagement recommendations. ’609 Patent at [54], 1:36–37. The ’964 Patent is titled “Predictive Analytics for Leads Generation and Engagement Recommendations” and is directed to an automated

predictive analytics system providing for generating sales leads with lead engagement recommendations. ’964 Patent at [54], 1:42–43. Claim 1 of the ’609 Patent recites: A computer-implemented method, wherein one or more computing devices comprising storage and a processor are programmed to perform steps comprising:

determining, using a computer, similarities between (a) fitness, engagement, and intent characteristics of a plurality of target clients and (b) fitness, engagement, and intent characteristics of an entity’s existing clients;

generating recommendations for engagement with the plurality of target clients, wherein components of the recommendations for engagement are based on determined similarities between (a) the fitness, engagement, and intent characteristics of the plurality of target clients and (b) the fitness, engagement, and intent characteristics of the entity’s existing clients;

categorizing a plurality of web pages, hyperlinks, and link structures located over the Internet using a trained classifier that uses features from content and code on web pages;

crawling, by a computer, the plurality of web pages, hyperlinks, and link structures based on the categorization of the plurality of web pages, hyperlinks, and link structures to collect third party unstructured text information; and

generating a feature matrix for the target client and comparing one or more value of the feature matrix of the target client with one or more values of a feature matrix for the entity’s existing clients to generate the recommendations of engagement.

’609 Patent at 17:12–39. Claim 1 of the ’964 patent is nearly identical, reciting: A computer-implemented method, wherein one or more computing devices comprising storage and a processor are programmed to perform steps comprising:

generating recommendations for engagement with the plurality of target clients, wherein components of the recommendations for engagement are based on determined similarities between (a) a fitness, engagement, and intent characteristics of a plurality of target clients and (b) a fitness, engagement, and intent characteristics of an entity’s existing clients;

categorizing a plurality of web pages, hyperlinks, and link structures located over the Internet using a trained classifier that uses features from content and code on web pages;
