The Sunny Optical Patent Portfolio offers a useful lens into how one of China’s largest optical component makers protects its engineering output. Across 3,773 total patent families, 80.9% remain active, covering both granted and pending cases. Of this body, 2,421 families have been granted and 630 are still pending examination, giving a grant rate of 64.2%. The remaining families, 722 in total, fall under lapsed, revoked or expired status. These figures describe prosecution and maintenance activity only, not a judgment on patent quality or enforceability.
Filing activity peaked in 2018, when the company filed 528 patent families in a single year, a level not matched before or since. China dominates the jurisdiction mix, accounting for 97.5% of filings across a portfolio that spans 8 jurisdictions. On the technology side, optical elements and systems under G02B lead the pack, with 1,902 families, well ahead of any other classification. This concentration tells a clear story about where Sunny Optical places its research priorities.
This report is meant to help readers understand filing patterns and patent portfolio health at a glance, not to serve as a substitute for legal or technical due diligence. Filing counts alone do not establish product success, market share, or competitive advantage in any given segment. Readers planning to rely on specific families for licensing, investment or litigation purposes should verify details independently. What follows is a structured walk through legal status, filing trends, geography and technology focus, built entirely on the patent data available for this company.

How Healthy is Sunny Optical Patent Portfolio?
Patent portfolio health starts with legal status, and the numbers here look reasonably strong. Granted families make up 64.2% of the total, with 2,421 patents already secured. Pending applications add another 16.7%, or 630 families, still working through examination. Combined, 80.9% of the portfolio sits in an active state, which signals ongoing commercial relevance rather than a legacy stockpile. The composition chart in this section shows how these categories break down relative to one another.
On the attrition side, lapsed families account for 11.3%, revoked ones for 5.8%, and expired filings for a smaller 2.0%. These are not unusual figures for a portfolio of this scale and age profile. Patent type adds another dimension worth noting. Standard patents represent 73.0% of filings, while utility models make up 27.0%. This split suggests Sunny Optical pursues full examination for its more significant inventions, while using utility models for faster, lower cost protection on incremental improvements, a common approach among Chinese manufacturers operating at high filing volume.
How Has the Sunny Optical Patent Portfolio Evolved Over Time?
Patent filing trends at Sunny Optical show a long climb followed by a recent pullback. Filings stayed in single or low double digits through 2012, then began accelerating sharply. By 2015, annual filings reached 157, and growth continued through 2017 at 257. The real surge came in 2018, when filings hit 528, the single highest year on record for the company. The filing-trend chart in this section traces this rise clearly against the quieter years before it.
After 2018, volumes eased to 455 in 2019 and settled into a range between roughly 270 and 450 through 2024. The most recent two years, 2025 and 2026, show sharply lower counts of 128 and 45 respectively, reflecting a -64.8% change in the latest year. This drop should be read with caution rather than alarm. Patent applications typically take 12 to 24 months to publish, so recent filings are likely undercounted in any live dataset. The real story is a mature, high-volume filer normalizing after an exceptional 2018 peak.
Where Does the Sunny Optical Patent Portfolio Prioritize Patent Protection?
Patent geography at Sunny Optical is heavily domestic. China accounts for 97.5% of all filings, by far the dominant jurisdiction, with 3,680 families filed there. This reflects both the company’s manufacturing base and the practical reality that Chinese utility models and patents are faster and cheaper to secure locally. The geographic chart in this section makes this concentration immediately visible against the other seven jurisdictions in the portfolio.
International filing exists but at a much smaller scale. WIPO PCT applications cover 13.2% of families, acting as a bridge toward potential international protection. The United States follows at 8.8%, India at 5.2%, and Europe at 1.9%, with Taiwan, Japan and South Korea each under 1.1%. This pattern suggests a filing strategy built primarily around protecting domestic manufacturing and supply chain advantages first, with selective international filing reserved for markets of particular commercial interest, likely tied to specific customer relationships or export volumes.
Where is the Sunny Optical Patent Portfolio Building Protection Across Key Technologies?
IPC analysis of the Sunny Optical Patent Portfolio points clearly toward optics as the technical core. The G02B class, covering optical elements, systems and instruments, leads with 1,902 families, or 39.9% of all classified filings. This aligns directly with the company’s core lens and camera module business. The technology chart in this section shows this category towering over every other classification in the portfolio.
Image and video processing under H04N ranks second at 27.0%, with 1,287 families, reflecting growing investment in how captured images get processed and displayed. Photography apparatus under G03B follows at 17.1%, or 813 families. Smaller but notable clusters include image data processing (G06T at 4.0%), navigation and radio direction finding (G01S at 2.5%), and image recognition (G06V at 1.7%). This tail of smaller categories hints at gradual diversification into computational imaging, sensing and vision recognition, areas that support automotive and AR/VR ambitions beyond traditional smartphone optics.
How Has the Sunny Optical Patent Portfolio Evolved Across Filing Geographies?
Looking at filings by year and jurisdiction together reveals how Sunny Optical’s international ambitions have shifted. Chinese filings grew steadily from 159 in 2015 to a peak of 470 in 2018, then stayed strong through 2024 at 264. This domestic base has remained consistently the largest contributor every single year. The heatmap in this section shows this steady domestic strength next to much more volatile international activity.
International filings tell a different story. WIPO PCT applications jumped to 107 in 2017 and 128 in 2018, then fell sharply to 12 by 2024. United States filings peaked at 95 in both 2017 and 2019, before dropping to single digits in recent years. India followed a similar pattern, rising to 74 in 2017 then falling close to zero by 2022. Japan and South Korea effectively stopped appearing in the data after 2018. This suggests a window of aggressive international expansion around 2017-2019 that has since narrowed considerably.
Consultant’s Perspective on Sunny Optical Patent Portfolio
Taken as a whole, the Sunny Optical Patent Portfolio reflects a company whose innovation engine is firmly anchored in optics, with ambitions that occasionally reach outward but ultimately return home. The 80.9% active rate and 64.2% grant rate point to a portfolio that is being actively maintained rather than left to lapse. That is a reasonably healthy signal for a manufacturer operating at this scale.
What stands out more is the geographic concentration. With 97.5% of filings in China, the company’s intellectual property strategy still looks primarily defensive and domestic, protecting manufacturing know-how rather than building a global enforcement position. The 2017-2019 push into the US, India and PCT routes, followed by a retreat, suggests either a change in international strategy or a shift toward trade secret protection abroad.
For a reader assessing competitive exposure or licensing opportunity, the technology concentration in G02B and H04N is the more actionable signal than raw filing counts. Sunny Optical’s bet on computational imaging and vision recognition, though still small in share, is worth watching closely over the next two to three filing cycles as automotive and AR/VR segments mature.
