Microwave Thermal Processing Patents: Who Leads, Gaps 2026
Microwave-Assisted Thermal Processing Patents: Filing Trends and White Space
One assignee dominates the ranked leaders, holding 10 records against a long tail where the fifth-ranked company holds only 3 and the tenth holds 1. Filings rose from 3 records in 2017 to a peak of 4 in 2022, with no sustained upward trajectory since. Because the corpus is small, single-year swings of one or two records look larger than they are; treat the shape as flat-to-modest rather than a growth curve. The 2026 count is partial and will rise as later filings publish.

Common questions on this landscape
Who holds the most patents in microwave-assisted thermal processing?
Within this dataset of 37 records, one assignee leads the ranking with 10 records, well ahead of the fifth-ranked company at 3 and the tenth-ranked at 1. That gap indicates a concentrated filing programme at the top rather than even competition across the ranked leaders. It is worth noting this ranking covers only the 10 companies the dataset returns, not every company that has ever filed in the space, so treat it as a view into the most active filers rather than an exhaustive list.
What technology areas do these patents actually cover?
The claims split mainly between food composition and formulation (IPC class A23L, on 56.8% of the 37 records) and electric heating circuitry (H05B, on 43.2%), with packaging (B65D, 29.7%) and domestic heating hardware (F24C, 24.3%) as secondary but non-trivial fronts. Because a single patent can carry multiple IPC codes, these percentages overlap and should not be summed. In practice this means a clearance search needs to cover both the food matrix and the RF delivery hardware, not just one side.
Is the filing rate in microwave-assisted thermal processing growing?
The data shows filings moving from 3 records in 2017 to a peak of 4 in 2022, without a sustained upward trend across the tracked years. There are too few complete years once publication lag is accounted for to state a reliable growth rate. The 2025-2026 figures are especially incomplete, since patents typically publish around 18 months after filing, so recent-year counts will rise as later filings become public.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
