LTI has full ownership of the following issued and pending patents. The patents fall into three types of technology:
Phrase-Based Formatting
Technology for reformatting text to improve the readability and legibility of text. The first patent (7,069,508) is a system that uses a neural net to analyze text and optimize the spacing between words to improve reading comprehension. The second patent (7,346,489), is a continuation of the first, which expands protection by providing broader coverage for using a neural net to determine phrasing and phrase boundaries in a text. The third patent (7,743,324), is also a continuation of the first, which expands protection by providing broader coverage for reformatting text to optimize spacing while maintaining the overall appearance of the original text. The fourth patent (8,209,601; issued June 26, 2012) further broadens protection beyond the second and third patents with less restrictive claim language on which spaces must be adjusted. This technology is used to adjust spaces to increase text comprehension by improving eye movements.
Bever, T. G., & Robbart, J. (Filed 7-13-2000/Issued 6-27-2006/Exp. 7-3-2023). System and method for formatting text according to linguistic, visual and psychological variables. U.S. Patent No. 7,069,508. Washington, DC: U. S. Patent and Trademark Office.
Bever, T. G., & Robbart, J. (Filed 5-10-2006/Issued 3-18-2008/Exp. 7-22-2026). System and method of determining phrasing in text. U.S. Patent No. 7,346,489. Washington, DC: U.S. Patent and Trademark Office.
Bever, T. G., & Robbart, J. (Filed 5-10-2006/Issued 6-22-2010/Exp. 3-12-2029). System and method of formatting text according to phrasing. U.S. Patent No. 7,743,324. Washington, DC: U.S. Patent and Trademark Office.
Bever, T. G., & Robbart, J. (Filed 6-10-2010/Issued 6-26-2012/Exp. 12-22-2030). System and method of formatting text. U.S. Patent No. 8,209,601. Washington, DC: U.S. Patent and Trademark Office.
Information-Based Text Composition
Technology for compositing a formatted text input to improve legibility, readability and/ or print economy while preserving the format of the text input and satisfying any user selected aesthetic constraints. This is accomplished by reading in blocks of text input, assigning an information measure to each character indicating the predictability of that character to differentiate a word from other words. An adjustment to a physical feature is determined for each character to control the visual prominence of that character according to the values of the assigned information measures. This technology is used to adjust letters and spaces to increase text comprehension by improving word perception and eye movements.
Bever, T. G., Nicholas, Chris. D., Hancock, R., Alcock, K. W., & Jandreau, S. M. (Provisional filed 9-28-2007/ Issues 11-6-2012/Exp. 8-8-2031). System, plug-in and method for improving text composition by modifying character prominence according to assigned character information measures. Patent No. 8,306,356. Washington, DC: U. S. Patent and Trademark Office.
Bever, T. G., Nicholas, Chris. D., Hancock, R., Alcock, K. W., & Jandreau, S. M. (Pending; Provisional filed 9-28-2007/divisional filed 9-30-2012). System, plug-in and method for improving text composition by modifying character prominence according to assigned character information measures. Serial No. 13/632,018. Washington, DC: U. S. Patent and Trademark Office.
Ebook Format
A system and method that arranges content to be legible and readable in a static, fixed-layout page size to match a specific display size providing the exact arrangement and appearance of the content as it will be displayed. The technology is based on files that are fixed-layout and paginated and because they are pre-composed are intended for optimal display on a particular device. The technology may be used to convert digital typesetting documents used in publishing (e.g. printed books) to a display-specific format for electronic publication while typesetting for a specific display. The technology must be used to compose unformatted source material to provide a certain "look and feel" (design) for a specific display. Although this approach requires considerably more resources to create a file for each display-specific format, the file provides unique typesetting, is more aesthetically pleasing, and is easier to read. This technology is used to deliver the first two technologies in ebooks to mobile devices.
Nicholas, Chris. D., Maher, E. J., Ashley, K. L., & Berendt, L. H. (Filed 2-1-2010/Issued 8-26-2014). System and method of converting the digital typesetting documents used in publishing to a device-specific format for electronic publishing. U.S. Patent No. 8,819,541. Washington, DC: U. S. Patent and Trademark Office.
Nicholas, Chris. D., Maher, E. J., Ashley, K. L., & Berendt, L. H. (Provisional filed 2-13-2009 / Utility filed 8-18-2014, Status Pending). System and method of converting the digital typesetting documents used in publishing to a device-specific format for electronic publishing. Application No. 14/462,118. Washington, DC: U. S. Patent and Trademark Office.
