Passive Insulated Pharma Shippers Patents: Leaders & White Space 2026
- Filing peaked in 2017 at 16 records and has fallen since, with 2021-to-2024 filings down -100% on the dataset's own comparison — though 2025-26 figures are still filling in given the ~18-month publication lag.
- One assignee leads at 23 records against a fifth-place figure of 7 and a tenth-place figure of 2, out of 12 ranked companies — a steep drop-off rather than a gradual one.
- B65D packaging claims dominate at 81.3% of the 75 records in scope, with F25D cooling claims close behind at 61.3% — most activity sits in container structure and thermal management, not adjacent mechanical or handling classes.
Filing growth compares 2021 (12 records) with 2024 (0) — 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.
What this landscape covers
This landscape tracks patent activity for passive insulated pharmaceutical shippers — reusable or single-use containers that hold a payload within a defined temperature range for a set hold time without active power, typically using phase change material or vacuum insulated panels. The search spans records published between 2015 and mid-2026, filtered to documents that combine container or shipper terminology with the specific technical vocabulary of conditioning procedures, payload volume and reusable design.
The 75 records in scope sit predominantly in container and packaging classifications, with a secondary concentration in refrigeration and cooling apparatus. Filing activity is uneven year to year, and the most recent years understate true filing volume because publication lags filing by roughly 18 months.
Filing trend and technology composition
Two views of the same 75-record dataset: how filing volume has moved year over year, and which IPC subclasses the claims fall into.
Filing trend, 2017-2026
Filings peaked at 16 in 2017 and declined thereafter; the dataset's own year-over-year comparison shows 2021's 12 filings falling to 0 by 2024, a -100% change over that three-year span. Treat 2025 and 2026 as incomplete rather than as evidence of a continued decline, since publication lag means recent filings have not yet all surfaced.
IPC subclass composition
B65D (containers and packaging) appears in 81.3% of the 75 records and F25D (refrigeration and cooling) in 61.3%, with B32B (layered products and laminates) a distant third at 29.3%. Because records can carry multiple classes, these shares sum to well over 100%; they show where claim language concentrates, not a partition of the field.
Shares are the percentage of the 75 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Thermally insulated shipping container with layered articulating vacuum insulated panels
A kit from which a thermally insulated shipping container may be assembled, built from an outer shell and four flat-stock vacuum insulated panels, each with three articulating sections that fold into 3-dimensional C-shaped units. The panels form nestable pairs that line the lower and upper portions of the outer shell to create a fully enclosed insulated payload chamber.Filed by Peli Biothermal, published 2019-08-08 as US20190241350A1.

Three read-outs from the dataset that matter more than the raw counts on their own.
Filing has cooled from its 2017 peak
The 16-filing peak in 2017 was not sustained; the dataset shows 2021's 12 filings dropping to 0 by 2024, the last year that can be treated as complete. That points to a field where the core mechanical approaches were staked out early rather than one still in a filing race.
One assignee holds a clear lead
Across the 12 companies in the ranking, the leader's 23 records dwarf the fifth-place figure of 7 and the tenth-place figure of 2. That gap suggests a single portfolio worth diligence before filing anything that touches vacuum insulated panel or nested-panel geometry.
Claims sit in container structure and cooling, not adjacent classes
The IPC composition is heavily weighted toward container/packaging (B65D) and refrigeration (F25D) classifications, with layered-materials claims (B32B) a distant third. Classes like heat-exchange apparatus (F28D) and box-making (B31B) appear in only a handful of records each.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to passive insulated pharmaceutical shippers, with the prior art for and against each one.
Who holds the ground and where it is open
The ranked assignees show where portfolio depth already exists; the gaps below show where claim language is thin.
A single assignee leads the ranked field
The top-ranked company holds 23 records against a field of 12 ranked assignees, with the fifth-place company at 7 and the tenth at 2. That distribution is a steep drop-off rather than a gradual tail, so freedom-to-operate work should start with this portfolio.
No ranked assignee shows recent-year filing momentum
The recent-year momentum figures show the ranked assignees, including the leader, at 0 filings in the latest year captured. Given the publication lag, this understates true activity, but it also means no single company is visibly accelerating right now.
Co-assignment is rare and concentrated in one pair
The strongest co-assignee relationship in the dataset appears three times, between an individual inventor-assignee and a corporate partner. Beyond that pair, co-filing is not a notable pattern in this field — most records carry a single assignee.

Where to take this analysis
The dataset points to a field with an entrenched leader and thin recent filing — here is how to use that.
Map claims against the leader's portfolio
Before drafting around vacuum insulated panel or nested-panel geometry, check claim scope against the 23-record leading portfolio identified in the ranking.

The assignee ranking for this dataset covers 12 companies, and one leads clearly with 23 records against a fifth-place figure of 7 and a tenth-place figure of 2. That gap indicates a single company has built the deepest portfolio in this space, making it the first stop for any freedom-to-operate review. The ranking is the complete list the data endpoint returns for this search, not a curated top-50 or top-100 cut, so smaller players genuinely file less here rather than being excluded by a cutoff.
Based on the complete years in this dataset, filing has declined: 2017 was the peak year at 16 records, and the dataset's own comparison shows 2021's 12 filings falling to 0 by 2024, a -100% change over that span. However, 2025 and 2026 figures should not be read as confirming further decline, because publication typically lags filing by around 18 months and recent years are still filling in. A fair read is that the field cooled after an initial wave of filing rather than that it is currently collapsing.
Claims concentrate heavily in container and packaging structure (B65D, 81.3% of the 75 records) and refrigeration or cooling apparatus (F25D, 61.3%), with layered materials such as vacuum insulated panel laminates (B32B) a distant third at 29.3%. Smaller classes like heat-exchange apparatus, pipe fittings and carton-making each appear in only a handful of records. This tells you where claim language is dense — container geometry and thermal insulation — and where it is comparatively thin.
US20190241350A1, filed by Peli Biothermal and published in 2019, covers a kit for assembling a thermally insulated shipping container from an outer shell and four flat-stock vacuum insulated panels, each with three articulating sections that fold into three-dimensional C-shaped units. The panels form nestable pairs that line the lower and upper portions of the outer shell to create a fully enclosed insulated payload chamber. Anyone designing a foldable or articulating vacuum-panel liner for a shipping container should read this filing's claims closely before finalizing a panel geometry.
Relative to the dominant B65D and F25D classes, this dataset shows only a handful of records touching heat-exchange apparatus (F28D, 3 records), pipe fittings for coolant routing (F16L, 5 records), and box-and-carton assembly methods (B31B, 2 records). These low counts suggest under-claimed technical branches rather than a lack of technical relevance, since thermal shippers routinely involve heat exchange and modular carton assembly. A first claim in one of these branches, drafted to connect it explicitly to hold-time or conditioning-procedure performance, would sit on much less prior art than a new container-shell claim.
