Run your analysis now →Filing growth compares 2021 (47 records) with 2024 (64) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 768 records in scope (CR5), not by the ranked leaders only.
This dataset tracks 768 published records at the intersection of optical interconnect, wireless die interconnect and inductive coupling link claims, filtered to documents that also address a practical constraint — channel loss, alignment tolerance, power efficiency, channel data rate, coupling capacitance or integration complexity. That second filter matters: it separates general optical-communications filings from the subset actually engineering the tradeoffs that determine whether a die-to-die link works at package scale. Coverage runs from 2015 through the 2026-07-31 cut-off, with publication lag meaning the most recent one to two years understate true filing volume.
The records span optical elements and systems, semiconductor device structures, general transmission, lasers, and printed-circuit assembly claims, reflecting how die interconnect work sits across optics, packaging and RF disciplines rather than inside a single IPC class.
Pick a task. Every answer cites the patents behind it.
Two views of the same 768 records: how filing volume moved year over year, and how the claim language splits across IPC subclasses.
Annual filings moved from 34 in 2017 to a peak of 64 in 2024, including a +36% rise from 47 in 2021 to that 2024 peak. The 2025 and 2026 figures (down to 3 in the partial latest year) reflect publication lag rather than an actual slowdown in filing.
G02B (optical elements & systems) appears in 47.4% of the 768 records, ahead of H01L semiconductor devices at 29.3% and H04B transmission at 19.0%. Because records can carry multiple IPC codes, these shares sum past 100% — the overlap itself shows how tightly optical, semiconductor and RF claims are intertwined in this space.
Shares are the percentage of the 768 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaAn optical interconnect device may include a multi-fiber connector at a first end of the optical interconnect device. The optical interconnect device may include an edge coupled connector at a second end of the optical interconnect device. The optical interconnect device may include a plurality of optical fibers disposed inside the multi-fiber connector and the edge coupled connector to optically couple the multi-fiber connector to the edge coupled connector, wherein the multi-fiber connector and the edge coupled connector rigidly interconnect to structurally support the optical interconnect device.Filed as a structural connector claim — the rigid interconnection between the multi-fiber and edge-coupled ends is the mechanical detail worth checking against any new coupler design.

With the top 5 assignees holding 34.1% of all 768 records and the top 10 holding 45.4%, more than half of the corpus sits with entities outside the ranked leaders. That is room for a new entrant to build a defensible position without immediately colliding with an incumbent's core claims.
G02B optical-element claims cover nearly half the corpus while H01S laser and stimulated-emission claims sit at just 9.2%. A drafting strategy anchored in laser-source integration, rather than generic optical coupling, faces a thinner prior-art base.
Filing volume rose 36% from 47 in 2021 to 64 in 2024, the last year that can be read as complete. The sharp drop shown for 2025 and 2026 reflects the roughly 18-month publication lag, not a cooling of activity.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to optical and wireless die interconnect, with the prior art for and against each one.

Ten co-assignee pairs appear in the data, with the strongest links running between a small cluster of university research groups, each pair sharing 16 co-filed records — a sign of sustained joint research programs rather than one-off collaborations.
The ranking spans 100 companies counted by record; a handful of large filers sit alongside a long tail of academic and single-filing entrants.
The leading assignee holds 97 records, more than three times the fifth-place total of 26. That gap suggests a sustained, multi-year filing program rather than opportunistic filing around a single product cycle.
Record counts fall from 26 at fifth place to 15 at tenth, a gentler slope than the gap between first and fifth. This is a field with several credible second-tier players rather than one dominant firm and a flat tail.
Most tracked assignees show flat or declining latest-year counts, consistent with publication lag rather than withdrawal from the space. Only one assignee in the momentum data posted a year-over-year increase, and off a small base.

The dataset points to specific next steps depending on whether the goal is freedom-to-operate, whitespace filing, or competitive tracking.
With 45.4% of records held by the top 10 assignees, any new filing in optical or wireless die interconnect should be checked against that concentrated set before drafting claims.
Explore assignee claims in EurekaLaser-source integration and inductive coupling capacitance tuning show lighter density than the core optical-element classes, and may offer cleaner claim space.
Map whitespace in EurekaMomentum data shows most assignees flat or declining in the latest year, which is expected given publication lag — but tracking the leader's filings as 2025-2026 data fills in will clarify whether its lead is widening.
Set up tracking in EurekaOne assignee leads the ranked field with 97 records, well ahead of the fifth-ranked assignee at 26 and the tenth-ranked at 15. The top 5 assignees together hold 34.1% of all 768 records in scope, and the top 10 hold 45.4%, meaning a large share of the field still sits outside the leading filers. This concentration pattern is typical of a technology area with a few sustained corporate research programs alongside many smaller or academic filers.
Filing volume grew from 47 records in 2021 to a peak of 64 in 2024, a 36% increase over that span, and 2024 is the most recent year that can be read as a complete filing year. The apparent drop in 2025 and 2026 is a publication-lag artefact — patents typically publish about 18 months after filing — not evidence of declining interest. Anyone assessing momentum should treat the last one to two years of any trend chart as understated rather than as a real slowdown.
Optical elements and systems (IPC class G02B) appear in 47.4% of the 768 records, making it the single most common classification, followed by semiconductor devices (H01L) at 29.3% and general transmission (H04B) at 19.0%. Because a single patent can carry multiple IPC codes, these percentages overlap rather than sum to 100%, which itself shows how closely optical, semiconductor and RF disciplines intersect in die interconnect claims. Laser-related claims (H01S) are comparatively thin at 9.2%, suggesting less crowded claim space there.
US10732366B2 claims an optical interconnect device with a multi-fiber connector at one end and an edge-coupled connector at the other, joined by optical fibers that are rigidly interconnected for structural support. The key claim element is the rigid mechanical coupling between the two connector types, not merely the optical path between them. Anyone designing a competing multi-fiber-to-edge-coupled connector should examine whether their mechanical joint avoids this rigid-interconnection structure or relies on a materially different coupling mechanism.
Relative to the dense optical-element and semiconductor-device claim base, sub-areas like laser-source integration for die-level links, inductive coupling capacitance tuning, and wireless die-to-die power efficiency show comparatively lighter claim density in this corpus. That does not guarantee an easy path to grant, but it indicates less prior art crowding than the core G02B and H01L classes. A practical next step is a targeted prior-art search within those specific sub-areas before committing to claim language.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
