当レポートでは、iPhone 7 Plusに採用されたKnowles社のMEMSマイク技術の特許状況を調査し、企業概要、特許のポートフォリオ、取得済み特許・出願中特許、特許と関連製品のマッピング、特許訴訟などについてまとめています。
Founded in 1946, Knowles offers a growing range of micro-acoustic, electro-mechanical, and related technology platforms to support its customers. Knowles was the first to introduce MEMS microphones to the market in 2003 and is now the world-leader in MEMS microphones, with its SiSonic technology. Knowles is Apple's main MEMS microphone supplier. Yole Développement estimates the sales of Knowles' MEMS microphones at $360M in 2016, giving the company over 40% of the market. That year, Knowles shipped over 1.55 billion MEMS microphones. Moreover, Knowles has filed several patent lawsuits in the last ten years against rival manufacturers. In this context, it is important to understand the links between Knowles' MEMS microphones and their related patents. Our partner, System Plus Consulting, analyzed the MEMS microphone components included in the iPhone 7 Plus, which was launched by Apple in September 2016. The smartphone contains four MEMS microphones: one front-facing top microphone, two front-facing bottom microphones and one rear-facing top microphone. Two different MEMS microphones from Knowles have been found in the iPhone 7 Plus, the KSM microphones, KSM1 or KSM2, and the KMM microphone, KMM1. The models are very similar and the study focuses mainly on the KSM format. Based on the features revealed by the microphone teardowns, we have identified the closest Knowles patents to these technologies, and describe the main claimed features. This helps understand the core technologies developed by Knowles in their MEMS microphones. Knowles microphones in the iPhone 7 Plus include technologies claimed in patents published in the early 2000s and in the mid-2010s. We have also observed new IP activity linked to these microphones. The technologies currently being developed could represent a new angle of attack for infringement litigation from Knowles after the wave of suits the company initiated over the last decade.
Combining the data obtained by System Plus Consulting's teardown of Knowles microphones in the Apple iPhone 7 Plus with Knowmade's IP analysis, this report highlights IP related to these MEMS microphones. Moreover, it analyzes Knowles' related patent portfolio in order to understand the company's IP strategy and to identify main IP competitors.
System Plus Consulting tore down the MEMS microphones of Knowles included in Apple's iPhone 7 Plus, launched in September 2016. Knowmade then compared the features revealed to Knowles' IP portfolio. The selected features are mainly related to the microphone package, diaphragm and backplate, which uses Knowles' free-floating technology. The report identifies key patents held by Knowles related to these technology features. For each product feature, we have established links between patented technologies, including legal status.
Knowles has filed patent infringement litigations related to only two patent families of its portfolio. Both families are related to MEMS microphones and to features identified in this patent-to-mapping report. Knowles has filed complaints against six different defendants, including its main IP competitors. The technologies claimed in these patents are key for Knowles.
We have analyzed Knowles' patents related to MEMS microphones found in the Apple iPhone 7 Plus, including publication trends, country of publication, main inventors, and identified IP competitors. The analysis of forward and backward citations shows that Knowles' portfolio is cited by many patent applicants. Combining the citation network with analysis of the content of citing/cited patents, we have ranked Knowles' IP competitors to establish a general view of the IP competitive environment.
