Scope of the report: This flash report provides a benchmarking of patent performance of top 20 MEMS companies. Methodology: - The top 20 MEMS companies were selected from the Yole Développement’s annual ranking - April 2013 based on 2012 MEMS revenues. - The Patent Activity Index, the Patent Quality Index and the Patent Strength Index were determined for each selected MEMS company. These three parameters are based on four criteria: Number of patent families, Average size of patent families, Share of granted patents and Citation ratio. - The data were extracted from the FamPat worldwide database (Questel-ORBIT) which provides 60+ million patent documents from 92 worldwide patent offices. - A keyword based patent search was performed in title, abstract and claims: MEMS, Micro-electro-mechanical, Microelectromechanical. - Searches were performed on August 22, 2013 hence patents published after this date will not be available in the report. - The term 'Patent' has been used as a collective term for Patents and Published Applications. - According to FamPat’s family rules (variation of EPO strict family), a Patent Family comprises patents linked by exactly same priority numbers (strict family), plus comparison of priority and application numbers, specific rules by country and information gathered from other sources (national files, legal status …). - For legal status of EP/WO patents, EPO Register Plus has been used.

4. Objectives and Methodology
Scope of the report:
This flash report provides a benchmarking of patent performance of top 20 MEMS companies.
Methodology:
• The top 20 MEMS companies were selected from the Yole Développement’s annual ranking - April 2013 based on 2012
MEMS revenues.
• The Patent Activity Index, the Patent Quality Index and the Patent Strength Index were determined for each selected MEMS
company. These three parameters are based on four criteria: Number of patent families, Average size of patent families, Share
of granted patents and Citation ratio.
• The data were extracted from the FamPat worldwide database (Questel-ORBIT) which provides 60+ million patent
documents from 92 worldwide patent offices.
• A keyword based patent search was performed in title, abstract and claims: MEMS, Micro-electro-mechanical,
Microelectromechanical.
• Searches were performed on August 22, 2013 hence patents published after this date will not be available in the report.
• The term 'Patent' has been used as a collective term for Patents and Published Applications.
• According to FamPat’s family rules (variation of EPO strict family), a Patent Family comprises patents linked by exactly same
priority numbers (strict family), plus comparison of priority and application numbers, specific rules by country and
information gathered from other sources (national files, legal status …).
• For legal status of EP/WO patents, EPO Register Plus has been used. For legal status of US patents, USPTO PAIR has been
used. For legal status of other patents, information have been gotten from their respective national registers.

5. Parameter Definition (1/2)
Number of Patent Families :
It represents the total number of patent families currently owned by a company. Despite quality considerations, it is still reasonable to assume that
the number of patent families positively affects firm performance. Large patent portfolios not only indicate stronger efforts in R&D activities and
therefore a higher innovative output. Large patent portfolios are also strategically useful, for example, to block competitors (Blind et al. 2006).
Additionally, larger patent portfolios increase the chance for licensing agreements or trade with other firms and can also be used to prevent smaller
potential competitors from entering relevant markets. Furthermore, patent output can be seen as a positive signal to the market (Neuhäusler et al.
2011). It is an indicator of the patent activity of a company.
Mean Size of Patent Families :
It represents the average number of countries in which protection is sought for the same invention. Given the costs required to file and enforce
patents in many countries, only those with sufficient expected value to their owners will be extended abroad, denoting an expected market for the
patented technology (N. van Zeebroeck 2009). It is an indicator of the patent activity of a company.
Share of Granted Patents :
A patent will only be granted if the technological invention consists of new technological elements. A granted patent can be seen as more valuable
than a non-granted patent as it has met the criteria of novelty, technological height and commercial applicability. Therefore, a granted patent is
believed to be of higher technological capacity than the mere patent application (Basberg, 1987). A larger share of granted patent leads to an
increase in market value and profit of firms. Here, the share of granted patents is measured as the number of patent families containing at least one
granted patent. The share of granted patent is an indicator of the patent quality of a company.
Citation Ratio :
The number of citations received by a patent in subsequent patent documents can be viewed as a sign for an economically important invention
(Albert et al. 1991; Narin et al. 1987). A larger average number of forward citations per patent has a positive effect on firm performance in terms of
market value and ROI (Neuhäusler et al. 2011). Here, we take the citation ratio which measures the number of patent citations over the number of
patent families. It reflects the mean number of citations received by the patent family. The citation ratio is an indicator of the patent quality of a
company.

10. Bullet Point Summary
• Texas Instruments, Hewlett Packard, Analog Devices and Freescale Semiconductor have the highest patent
activity/quality index in MEMS technology.
• Invensense has the highest degree of specialization in MEMS with more than 50% of its patent portfolio related to MEMS
technology, followed by Knowles Electronics (12%) and Analog Devices (8%). The most of top 20 MEMS companies have a
low degree of specialization. Indeed, the patents related to MEMS technology only account for less than 2% of the whole of
their patent filings.
• A positive Patent Strength Index seems to be a necessary condition to generate high revenues. Thus, this index may be
used as a quite good indicator for potential revenue generation. Despite an equivalent Patent Strength Index, Panasonic,
Freescale, Analog Devices and Honeywell generated less MEMS revenues in 2012 than STMicroelectronics, Texas
Instruments, Bosch and Hewlett Packard. This may be due to oldest MEMS technologies and/or a position in low-growth
markets.
• The degree of specialization in MEMS has no influence neither on Patent Strength Index nor revenue generation.
