10 Plaintiff, ORDER

11 v.

12 Microsoft Corporation,

13 Defendant. 14 15 Pending before the Court is Defendant Microsoft Corporation's ("Microsoft") 16 Motion to Dismiss. (Doc. 16.) This matter has been fully briefed. (Docs. 16, 18, 20.) On 17 March 19, 2024, the Court held oral argument. For the reasons set forth below, the Court 18 will grant the motion with leave to amend. 19 I. Case Background 20 Language Technologies, Inc. ("LTI") brought suit against Microsoft Corporation 21 ("Microsoft") for patent infringement. (Doc. 1.) LTI alleges that Microsoft's "Bling FIRE 22 Tokenizer"1—used in, among other things, Microsoft's Bing search engine—infringes on 23 U.S. Patent No. 7,069,508 ('508 Patent) and U.S. Patent No. 7,346,489 ('489 Patent) owned 24 by LTI (collectively "the Patents"). (Id. at 14–17.) 25 II. The Patents 26 In 2000, LTI filed for the '508 Patent for a "System and Method for Formatting Text

27 1 In the realm of natural language processing and machine learning, tokenization refers to 28 the process of parsing text into smaller bits of data, including sentences, phrases, words, or even characters. 1 According to Linguistic, Visual and Psychological Variables." (Doc. 1-2 at 2.) The '508 2 Patent was issued in 2006. (Id.) The patent describes an "invention [that] analyzes text and 3 reformats it to establish optimal spacing and related features for readability, reader 4 comprehension and publishing economies." (Id. at 7.) "The invention has a neural network 5 that uses a library of text data to analyze text and determine phrases. The text is then 6 formatted according to the determined phrases. The neural network learns additional phrase 7 indicators as it analyzes text and adds the additional data to the library." (Id.) The '508 8 Patent provides an alternative to this embodiment saying that "an expert system can be 9 established having rules and templates to be used for analyzing text or the neural network 10 can be used to develop such an expert system." (Id.) The '508 Patent describes a method 11 whereby input comes "from any one of a number of different types of devices such as a 12 computer keyboard, a client computer, or a speech recognition device[]" and "output can 13 be used for a number of different types of reading material including printed books, 14 electronic books, Web pages, direct mailing literature, and closed caption systems." (Id.) LTI alleges that Microsoft infringed on Claim 23 of the '508 Patent. (Doc. 1 at 14.) 15 Claim 23 reads: 16 A computer-implemented method for formatting text, 17 comprising the steps of: 18 (a) providing text input; 19 (b) providing a library of key words and punctuation 20 definitions that identify the beginning or end of a phrase; (c) using said key words and punctuation definitions to 21 determine characteristics that predict boundary punctuation; 22 (d) examining a plurality of words of said text input; 23 (e) using said determined characteristics to predict phrase boundaries within said plurality of words; 24 (f) repeating steps d–e for a next plurality of words until all 25 the text input has been analyzed; and (g) formatting said text input according to the predicted 26 phrase boundaries. 27

28 (Doc. 1-2 at 11.) Claim 23 is representative of the '508 Patent for purposes of this Motion 1 to Dismiss because the other claims are substantially similar. Content Extraction & 2 Transmission LLC v. Wells Fargo Bank, Nat'l Ass'n, et al., 776 F.3d 1343, 1348 (Fed. Cir. 3 2014). The parties have also agreed that Claim 23 is representative. (Doc. 16 at 10 n.3; 4 Doc. 18 at 7 n.2.) 5 In 2006, LTI filed for the '489 Patent for a "System and Method of Determining 6 Phrasing in Text." (Doc. 1-3 at 2.) The '489 Patent was issued in 2008. (Id.) It is almost 7 identical to the '508 Patent. (See id. at 7–10.) LTI alleges that Microsoft infringed on Claim 8 1 of the '489 Patent. (Doc. 1 at 15.) Claim 1 reads: 9 A method for determining phrasing in text, comprising the steps of: 10 (a) providing text input; 11 (b) providing a library of key words and punctuation 12 definitions that identify the beginning and end of a phrase; (c) using said key words and punctuation definitions to 13 determine characteristics that predict phrase or sentence 14 boundaries; (d) examining a plurality of words of said text input; 15 (e) using said determined characteristics to predict phrase 16 boundaries within said plurality of words; and (f) repeating steps d–e for a next plurality of words until 17 phrase boundaries are predicted for each between words 18 between word space in the text input. 19 (Doc. 1-3 at 10.) Claim 1 is representative of the '489 Patent because it is substantially 20 similar, Content Extraction, 776 F.3d at 1348, and the parties have agreed that it is 21 representative (Doc. 16 at 10 n.3; Doc. 18 at 7 n.2). 22 III. Motion to Dismiss 23 On January 25, 2024, Microsoft filed a Motion to Dismiss Under Federal Rule of 24 Civil Procedure 12(b)(6). (Doc. 16.) LTI filed a Response (Doc. 18) and Microsoft 25 followed with its Reply (Doc. 20). Microsoft seeks to dismiss both claims in the Complaint, 26 arguing that the Patents are not eligible for patent protection under 35 U.S.C. § 101 as 27 interpreted by Alice Corporation Pty. Ltd. v. CLS Bank International, 573 U.S. 208 (2014). 28 (Doc. 16 at 1.) Microsoft contends that the Patents are merely "abstract mental processes 1 with generic computer technology . . . ." (Id. at 2.) 2 Specifically discussing the '489 Patent, Microsoft argues "[C]laim [1] is directed to 3 an abstract idea of identifying phrases in text by evaluating words and punctuation used in 4 the text. But the human mind practices this when writing, reviewing, or editing text." (Id. 5 at 11.) This is similar to, if not more abstract than, claims that other courts have found 6 patent ineligible because, Microsoft explains, "the idea of identifying phrases in text by 7 evaluating words and punctuation is simply the idea of evaluating data (words and 8 punctuation in text) to recognize some information about the data (phrases in the text)." 9 (Id.) Microsoft reiterates these arguments against the '508 Patent, although the '508 Patent 10 discloses an additional step of formatting the input text. (Id. at 12.) Microsoft argues that 11 the formatting step is similarly abstract and does not save the '508 Patent because "such 12 formatting has been in the realm of human knowledge since at least the advent of 13 typesetting . . . ." (Id.) 14 Furthermore, Microsoft hones in on the lack of specificity regarding how the Patents' methods rely on computer implementation and computer technology. (Id. at 13.) 15 Microsoft emphasizes that Claim 23 of the '508 Patent only mentions that the method is 16 "computer-implemented," and Claim 1 of the '489 Patent does not even specify computer 17 implementation. (Id.) Microsoft also argues that the Patents disclose the use of 18 conventional neural networks, "[b]ut nothing in the few general lines of patent description 19 on the subject suggests that the described 'neural network' was inventive or anything other 20 than generic." (Id.) Moreover the methods do not even require a neural network but "can 21 be implemented on any type of generic computer" and reliance on conventional computer 22 technology to merely carry out an otherwise abstract function is not patent eligible material. 23 (Id.
