Patent Landscape Report on Smart Contact Lens

  1. 1. USING PATSEER TO SEARCH & ANALYZE PATENTS ON SMART CONTACT LENS Note: All analysis and charts shown in this report have been prepared online using PatSeer. This report should not be construed as business advice and the insights are not to be used as the basis for investment or business decisions of any kind without your own research and validation. Gridlogics Technologies Pvt. Ltd disclaims all warranties whether express, implied or statutory, of reliability, accuracy or completeness of results, with regards to the information contained in this report.
  2. 2. Smart Contact Lens - Overview • Smart Contact Lenses are lenses which help in monitoring blood sugar levels in people with diabetes or look for signs of glaucoma and other diseases. The lenses could also map images directly onto the field of view, creating head-up displays for the ultimate augmented reality experience, without wearing glasses or a headset. To produce such lenses, researchers are merging transparent, eye-friendly materials with microelectronics • Evolution of contact lenses started in 1508 when Leonardo da Vinci conceptualized the first contact lens • Then in 1827 a British astronomer proposed the idea of making a mold of a human eye that could fit the curvature of the eye • In 1936, William Fienbloom developed a hybrid contact lens using glass and plastic materials • In 1959, first hydrophilic water absorbing hydrogel soft contact lenses were made. In 1971 first soft contact lens was approved by FDA in United States • In 2008, as a proof of concept, Babak Parviz at the University of Washington in Seattle created a prototype contact lens containing a single red LED. Using the same technology, he has now created a lens capable of monitoring glucose levels in people with diabetes. Parviz's design calls for the contact lens to send this information wirelessly to a portable device worn by diabetic patients, allowing them to manage their diet and medication more accurately • In 2014 Google announced a smart Contact Lens that can continuously monitor glucose levels in tears • The application domains of these so-called ’smart’ contact lenses have up till now been mainly limited to biomedical sensing and augmented reality
  3. 3. Search methodology and steps followed to accumulate patent data Using PatSeer, we searched individual publications and then collapsed them to one member per Family (Simple Families). Patent families is a group of one or more patent applications in multiple countries which represent the same invention. The publications included in the report are updated as of 30th June 2016. (TACD:((smart) wd2 (contact or intraocular or disposable or bionic) wd2 lens*) OR TAC:((camera or sensor or sensing or actuat?r or antenna*) w5 (contact lens*))) 1. We started with a set of 322 records (unique families). After manual review of the complete data set, we came across some irrelevant records which were removed 2. We flagged/rated each individual record using Search Recall™ option present in PatSeer 3. We then filtered, analyzed and came across some unwanted records 4. After analyzing those unwanted records we restricted our search to filings post 2000 5. After all the above steps we came to an accurate data set of 97 families, which were considered for all the analysis covered in this report 6. These results were moved to PatSeer project for further analysis This report analyzes research trends of smart contact lens with a focus on components, sensors and materials involved and also highlights the key companies involved in this space.
  4. 4.
