Legal research platform Casetext Inc. is entering the patent space with its latest product, CARA Patent, scheduled for release in early 2020.
CARA Patent is the latest expansion from Casetext, which launched in 2013 as a legal research tool to search documents online, after securing early backing from the Y Combinator. In 2016 Casetext released the CARA (Case Analysis Research Assistant) platform, which leverages artificial intelligence to find cases that are relevant to briefs.
After raising $12 million in March 2017, the company also released CARA Brief Finder, a companion platform that allows CARA users to place and research briefs, memos and other legal documents into its system.
Now, the young company is shifting its tech abilities into researching litigators' patent-related matters.
What it is: CARA Patent is a platform to help lawyers find the most relevant opinions, decisions and related IP connected to their patent.
With the drag and drop of a Microsoft Word document and PDF file into CARA Patent, the software analyzes the document's citations and key terms, and co-references those with district court motions and Patent Trial and Appeal Board (PTAB) opinions, explained Casetext co-founder and chief product officer Pablo Arredondo, who was formerly an IP litigator at Kirkland & Ellis.
CARA Patent can shorten the time it takes to research relevant decisions related to the patent or similar patents, Arredondo said. In a demo shown to Legaltech News, a query can net 1,000 search results, but Arredondo noted the results can be filtered by motion type, cause of action and various parameters, including claim construction, a process unique to the patent world.
Under the hood: CARA Patent leverages artificial intelligence, specifically natural language processing, to review statutes and cases to catch the subtle connections between words and phrases.
CARA Patent is the first practice-specific solution under the CARA brand. Casetext began working on a patent-specific upgrade after realizing that clients were using CARA specifically for patents, Arredondo said.
He added that CARA Patent now allows these clients to analyze how patents cite to other patents and cases, a feature not currently offered in CARA.
Competition: CARA joins a growing number of legal tech solutions that have been developed to automate and streamline some of the patent practice's complexity. From TurboPatent's RoboReview "bot" that edits and flags any formatting and concept errors, to InnVenn leveraging Venn diagrams to narrow the process of finding relevant patent results, entities have attempted to translate and streamline the dizzying patent process over the past few years.
Most recently, Similari also launched a patent search program, that leverages natural language processing to search published patents, similar to CARA Patent.
However, Arredondo said CARA Patent differs from the competition because most patent tools are built for surviving the "trenches" of litigation. "Once you actually declare litigation, this is where we help you win the litigation."
He explained that CARA Patent provides the patent-specific decisions and research needed to successfully litigate their patent, not just file a patent.
Arredondo also noted although Westlaw and ROSS's EVA offer similar "drag and drop" techniques for researching legal briefs that contain citations, CARA Patent is the only platform that allows users to search a patent.
