Overview:

The focus of this report is to create a broad connected medical hearables intellectual property landscape that spans both the classical hearing aid businesses as well as the advanced earphone and earbud market. The domain collection for this landscape was created with a two-stage querying process of Google’s BigQuery “patents-public-data:patents” dataset and the “publications” table. The first query isolated patent documents by searching (abstracts, descriptions, and claims) for terms relating the documents to ear-wore and hearing aid inventions such as “earbud”, “in-ear”, “ear-worn”, and “hearing aid”, and variations of those phrases. The second query then refined the domain collection to focus specifically on the connected medical hearables segment using the terms “medical”, “wireless”, and “sensor.” The Google patent dataset used in this analysis is current with patent documents filed through December 5, 2019. The resulting domain collection consists of 7,830 patent applications, of which 4,086 have been granted as patents. See the following link for more information on the patent landscaping process used in this report. https://www.moellerventures.com/index.php/blog/25-2020-articles/46-iplandscapes-process-descriptions

The report sections below consist of a results summary, a market intelligence brief, profiles of the notable top 25 corporate assignees, as well as tables presenting the details of the patent document landscape. These patent document landscape tables cover a profiling of the domain collection (Exhibits 1, 2, 3, 4), tabulations of inventors (Exhibit 5) and assignees (Exhibit 6), an analysis of the most referenced citations (Exhibits 7, 8), and a break-down of the technology classification CPC group codes (Exhibits 9,10,11). All the tables in this report (as available on https://www.moellerventures.com/) are interactive and can be sorted and searched via the column headings and available keyword search boxes with each table.

Results Summary:
  • The hearables intellectual property profiled in this report represents initiative of companies that span a variety of segments including enabling technologies, hearing aid product suppliers, advanced earbud suppliers, as well as patent holding companies and businesses more on the periphery of hearables that integrate the technology into other products. This breadth is representative of the broad methodology used to construct the domain collection and, in general, is a good profile of the hearables market.
  • From a market perspective the new hearables segment represents a collision of two market factors, which include the deregulation of the hearing aid industry and the development of the advanced wireless earbud market. This sets up some interesting market dynamics between the traditional hearing aid companies such as Cochlear and Oticon (Demant Group) and advanced earbud suppliers such as Apple, Samsung, and Sony. Overall, it’s estimated that the hearable market is positioned to grow at over 15% annually and reach an $80 billion to $90 billion market size in the 2025-2026 timeframe. See the Market Intelligence section below for more information.
  • The timeline of hearables patent filings (Exhibit 4) shows steady growth over the last 20 years from relatively insignificant levels to very active patent filings within the last five years. Projecting this trend forward in combination with the activity surrounding new features and functionality is likely to result in a continued high level of patent filings.
  • Qualcomm surfaces as the #1 assignee in the landscape, which shouldn’t be a surprise given that “wireless” was used as a required term in the domain collection creation query. Using “wireless” as the criteria to represent the connected capability of connected health hearables, will almost always reveal Qualcomm as a significant intellectual property holder. However, wireless and Qualcomm’s IP is technically positioned as enabling technology. Qualcomm isn’t in the hearables product market except as it supplied integrated circuits into product companies.
  • Another enabling technology company ranking in the top 10 is Witricity Corporation (#7 assignee), which focuses on wireless power transfer and battery recharging technology. The position of this company represents the importance of this technology to the usability factor of hearables (expressed in the company’s patents via various embodiments), and the fact that plug-in recharging techniques just doesn’t work with devices small enough to fit in a user’s ear. The importance of this technology is reinforced via the Citations Sorted by Assignee table (Exhibit 8) which shows that the #2 and #3 notable citations portfolios are by Nigel Power LLC and Access Business Group International which both have IP holdings associated with inductive power transfer.
  • Valencell is another enabling technology company ranked as the #18 assignee. Valencell focuses on biometric sensor technology for not only hearables but also the broader wearables product market. It has a sizable patent portfolio and intellectual property licensing business.
  • The traditional hearing aid companies are also represented on the assignee list with Cochlear and Oticon ranked in the top 25 and a couple of the other hearing aid competitors ranked lower on the list (Starkey #67, GN Resound #225).
  • Advance earbud IP is represented in the landscape top 25 assignees via Apple, Samsung, Sony, and Panasonic. This will be an interesting segment to watch as these companies add new technological capabilities and compete for differentiating advantages by utilizing and enforcing IP in the marketplace. It’s likely that these companies will also leverage the over-the-counter and direct-to-consumer business models to pursue applications in the traditional hearing aid market that are enabled by the Hearing Aid Act of 2017. See Market Intelligence section below.
  • Hearing aid companies are certainly not idle in regard to innovation and are developing new technologies, filing new IP, and leveraging partnerships to better pursue the advanced earbud market. This is exemplified by Cochlear’s partnership with Apple and Oticon’s development efforts focused on machine learning, AI, and personal assistant interfaces. See the brief company profiles below.
  • The hearables landscape also reveals two patent holding companies, Elwha LLC (#9 assignee) and Searete LLC (#16 assignee), both of which are subsidiaries of Intellectual Ventures. Intellectual Ventures is a business involved in the acquisition, licensing, and assertion of patents and through these subsidiaries controls IP that address the hearables market. See the brief company profiles below.
Market Intelligence:

The hearables market is currently experiencing dynamic changes as a result of two high-level market forces that are colliding and creating the new market for in-ear wearabes. The deregulation of the hearing aid industry and the emergence of smart wireless earbuds are the colliding forces that are creating an over-the-counter (OTC), direct-to-consumer, hearables market for products that not only augment hearing but will provide advanced capabilities to automatically adjust hearing experiences and provide interfaces to a variety of smart devices and personal assistants.

The deregulation of the hearing aid business was set into law via the FDA Reauthorization Act of 2017, which included the Over the Counter Hearing Aid Act designed to provide greater public accessibility and affordability with hearing aids. Prior to this law hearing aids were required to be purchased from and administered by licensed professionals. The devices cost thousands of dollars and are generally not covered by Medicare or most insurance companies. Under the new law hearing aid devices for people with mild to moderate hearing loss can be purchased over the counter and without any assistance from a licensed professional. This has setup a direct collision with the audio earphone and advance earbud market.

The earphone and earbud market has advanced rapidly in just the last few years with wireless capabilities, noise cancellation and advanced audio processing, and interfaces to a variety of platforms that augment the entertainment value and functionality of the devices. Smart earbuds are delivering connectivity not only to mobile phones but also tablets, PCs, and smart home systems. These devices are leveraging biometric technology to measure and monitor heart rate, blood pressure, body temperature and other characteristics for fitness and connected-health applications. Some devices are even enabling real-time language translation capabilities that work in conjunction with your mobile phone. If that weren’t enough, these devices are already sold via over-the-counter and direct-to-consumer channels that position them to better pursue the classical hearing aid market via the 2017 Hearing Aid Act.

The market for advanced hearables is growing on both fronts with hearing aids and advanced earbuds. Due to the cost and reimbursement dynamics of the classical hearing aid market, it’s estimated that only 20 to 30 percent of the people who can benefit from hearing aids actually get them. The Over the Counter Hearing Aid Act of 2017 has thus positioned that market to expand significantly to an 80% larger addressable customer base with lower prices and improved availability. That’s combined with the advanced earbud market which is also exhibiting substantial growth. Apple introduced its AirPod wireless earbuds in the fall of 2017. It’s estimated that Apple sold 60 million AirPods in 2019 amounting to a ~50% market share based on units and a ~70%+ market share based on revenue. The overall hearables market is expected to grow at a cumulative annual growth rate (CAGR) of greater than 15% and have a $80 billion to $90 billion market size in the 2025-2026 timeframe.
