Run your analysis now →Filing growth compares 2021 (61 records) with 2024 (14) — 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 2,045 records in scope (CR5), not by the ranked leaders only.
Starch byproduct valorization spans the patenting around turning corn wet-milling and starch processing residues — corn gluten feed, steep liquor, fibre fractions — into higher-value outputs: animal feed, fermentation feedstocks, protein concentrates and industrial polysaccharides. The search set combines byproduct-specific terms with process markers like protein concentration, fibre drying and feed value, which pulls in both the agricultural biotechnology side (genetically modified maize, enzyme production) and the downstream processing side (drying, feed formulation, market outlets for the resulting material).
The 2,045 records in scope run from 2015 through the 2026-07-31 cut-off, with a strong early peak and a documented pull-back since 2021 that reflects publication lag as much as any real slowdown in filing activity.
Two views of the same 2,045-record set: how filing activity has moved year over year, and which IPC subclasses carry the claim volume.
Filings peaked at 115 in 2017. The 2021-to-2024 span, the last period the dataset can treat as complete, shows a drop from 61 to 14 records — a 77% decline. Counts for 2025 and 2026 are still filling in given the roughly 18-month lag between filing and publication, so they should not be read as a continuing fall.
C12N (microorganisms and genetic engineering) touches 48.7% of the 2,045 records, ahead of A23K animal feed (32.6%) and C12P fermentation and enzymatic synthesis (31.2%). A23L foods (17.7%), A61K medicinal preparations (13.9%) and A01H plant breeding (13.5%) form a second tier. C08B polysaccharide derivatives (9.8%) and C07K peptides and proteins (9.2%) are the thinnest of the tracked classes, which is where downstream material-science claims have the most room.
Shares are the percentage of the 2,045 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaCattle feed blocks made by a low-cost process built on corn industry byproduct residues: corn gluten feed or corn steep liquor (or both) acts as a hardening agent. Molasses and hot water go into the mixer first, clay is added to keep ingredients in suspension, then animal fat, vitamins and other ingredients are mixed in and the batch is brought to 140–175°F before magnesium oxide and vegetable matter are added.Filed by Consolidated Nutrition, L.C., dated 1987-11-24 — one of the earliest documented uses of corn steep liquor as a functional hardening agent in feed blocks, well ahead of the 2015-2026 filing window this landscape otherwise tracks.

The leading assignee alone accounts for 173 records, and the top ten combined reach 57.8% of all records in scope. Below that threshold, filing activity thins out quickly across the remaining ranked assignees, which is typical of a field anchored by a few large agricultural biotech and ingredients players.
Filings peaked at 115 in 2017 and the 2021-2024 window shows a clear pull-back. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures are still incomplete and should not be read as evidence the field has kept falling.
Microorganism and genetic-engineering claims (C12N) touch nearly half the record set, while peptide and protein claims (C07K) and polysaccharide-derivative claims (C08B) sit under 10% each. That gap suggests downstream material characterization of the byproduct itself is comparatively under-claimed relative to the upstream biology.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to starch byproduct valorization, with the prior art for and against each one.
The assignee ranking is led by a small group of agricultural biotechnology and ingredients companies, with the remainder of the 100 ranked assignees filing far less densely.
The leading assignee's 173 records sit well above fifth place (127) and tenth place (60), a gap that signals a genuinely dominant filer rather than a tightly bunched top group.
Assignees that built substantial portfolios earlier in the window show zero records in the most recent year tracked. Given the publication lag, this is as likely to reflect filings still working through the pipeline as an actual stop in R&D.
Only ten co-assignee pairs appear in the data, and the strongest pairs are repeat inventor-employer combinations within single large organisations rather than cross-company joint filings, suggesting most of this work is done in-house.

The landscape narrows down to specific questions once you know where the density sits.
Concentration at the top of the ranking means clearance work should start with the leading assignees' families, not a flat search across all 100 ranked entities.

Set up a filing-trend alert in EurekaC08B and C07K sit well below the microorganism and feed classes; a targeted search there can surface whether that is genuine white space or simply unindexed prior art.
Explore IPC white space in EurekaThe dataset's assignee ranking is led by a single company with 173 records, well ahead of the fifth-place assignee at 127 and tenth place at 60. The top five assignees combined hold 36.1% of all 2,045 records in scope, and the top ten hold 57.8%. Below the top ten, filing density drops off quickly across the remaining ranked assignees, which include large agricultural biotechnology, enzyme and ingredients companies.
Filings peaked in 2017 at 115 records and have declined since, with the most recent complete window (2021 to 2024) showing a 77% drop from 61 to 14 records. However, publication lags filing by roughly 18 months, so 2025 and 2026 figures in the dataset are still incomplete and should not be read as proof the field is still cooling. The safest read is that activity has genuinely pulled back from its 2017 peak, with the very latest trend still uncertain.
US4708877A, filed by Consolidated Nutrition, L.C. and dated 1987-11-24, covers a process for making cattle feed blocks using corn gluten feed or corn steep liquor as a hardening agent, combined with molasses, clay, animal fat and vitamins mixed and heated to a specific temperature range. It is a process patent tied to that specific formulation and temperature sequence, not a blanket claim over using starch byproducts in feed. Anyone designing feed blocks with different binder chemistry, mixing order or temperature profile is working outside its literal claim scope, though it remains useful prior art to check against for near-identical formulations.
C12N, covering microorganisms and genetic engineering, appears in 48.7% of the 2,045 records in scope, making it the densest class by far, followed by A23K animal feed at 32.6% and C12P fermentation and enzymatic synthesis at 31.2%. C08B polysaccharide derivatives (9.8%) and C07K peptides and proteins (9.2%) are comparatively thin, suggesting more room for claims focused on the material chemistry of the byproduct itself rather than the upstream biological production route. These are shares of the full record set, and records can carry more than one class, so they do not sum to 100%.
Independently, for the most part. The dataset identifies only ten co-assignee pairs across the full set of 2,045 records, and the strongest of those pairs are repeat combinations of a company and its own named inventors rather than partnerships between separate companies. That pattern suggests most patenting in starch byproduct valorization happens inside single organisations, with limited formal cross-company collaboration visible in the assignee data.

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.
