Overview
What this dataset covers
This landscape draws on a search for records combining gene expression microarray or DNA microarray language with classification or diagnostic-signature terms, tied to disease or tumor context. The result set spans 140 published records, de-duplicated into 40 simple patent families. No date limit was applied to the search string, so the set reflects every matching record the search string returns, not a chosen period.
At 40 families, this is a small pool. The page is a starting point for a more targeted search, not a map of the field: absence of a name or a branch here is as likely to reflect the search terms as any real gap.
Records vs. families in scope
Counted over all 140 published records, including filings from before 2007; the filing-trend chart below covers only the 104 records from 2007 onward, so the two charts are not the same set of documents. Ordered by volume only, not by importance or claim strength. Counted in simple (DOCDB) patent families, so one invention filed in several countries counts once. Names come from Patsnap's standardised assignee field as recorded on each document; subsidiaries and group companies are not merged. The icon before each name is read from the name itself (words such as University, Institute or Ltd); the data carries no organisation-type field, so treat it as a reading aid rather than a classification. Filings held by named individuals rather than organisations are removed where they can be identified (33 here); that identification is not exhaustive, so an individually held filing can still appear below. Either way those filings stay inside the totals above. This table shows the top 25 of the 25 filers returned for this search; the data endpoint returns at most 100 entities, so even that 25 is not the complete set of filers. A single family can name more than one filer, so these counts overlap and do not add up to the total.

The Numbers
Filings, classes and offices
Figures below are read directly from the retrieved set: published records, simple patent families, IPC subclass shares and receiving offices.
Filing trend by earliest filing year (published records) (104 of 140 published records)
Records run from 2007 (24) to a peak of 27 in 2020. Years from 2022 onward are still filling in as later filings publish, so the most recent part of the chart understates eventual totals; this is a publication-lag effect, not a change in filing activity.
Counted in published records by earliest filing year, not de-duplicated into families. A filing is counted in the year it was filed, but it only becomes visible after it publishes: roughly 18 months for most routes, and up to 30 months where a PCT application enters national phase. 2022 onwards are therefore still filling in and are shaded; no growth figure on this page uses them. Because this series counts documents rather than inventions, a rise can mean more inventions or the same inventions filed in more countries; this dataset cannot separate the two. This chart covers 2007-2026 (104 records); the 140 total quoted above includes earlier filings outside the window.
IPC subclass composition (share of 40 simple patent families)
C12Q (measuring/testing involving enzymes or DNA) appears on 82.5% of families, the highest share of any subclass, followed by G01N (material analysis and testing) at 57.5%, G06F (electric digital data processing) at 30.0%, G16B (bioinformatics) at 22.5% and C12N (microorganisms and genetic engineering) at 15.0%. Because a family can carry more than one class, these shares add to more than 100% and are not mutually exclusive.
Shares are the percentage of the 40 patent families in scope. One patent family can carry several IPC classes, so the shares add up to more than 100%.

What the figures show
Three figures worth sitting with before treating any single name or class as representative of this small pool.
Largest single filer
6 of 40 families
15.0% share
The Board of Trustees of the Univ of Arkansas
This entity is named on 6 of the 40 simple patent families in scope (15.0%), the highest single-row figure among the 25 listed filers. The filer list is not rolled up to corporate group, and this share belongs to this row alone; it is not added to any other row with a similar name.
Counted in simple patent families.
Spread across filers
21 of 25
filers hold 2 or fewer families
Most listed filers hold a small number of families
21 of the 25 listed filers are named on 2 or fewer simple patent families each. Filer rows can overlap because one family may name several filers, so these counts are not summed into a combined share anywhere on this page.
Counted in simple patent families, listed filers only.
Legal status
22 of 140
records in force at retrieval
16% of records were granted and in force
22 of the 140 published records (16%) were granted and still in force at the retrieval date of 2026-10-27. The remaining records are pending, withdrawn, refused, lapsed or not determinable, and this dataset does not break that remainder down further.
Status as of 2026-10-27, counted in published records.
IPC composition
82.5% of 40 families
carry C12Q
C12Q appears on the largest share of families
C12Q (measuring and testing involving enzymes or DNA) is present on 33 of the 40 simple patent families (82.5%), the highest of the subclasses shown. G01N follows at 57.5%. Because one family can carry multiple IPC classes, these percentages add to more than 100% and do not partition the dataset.
Counted in simple patent families; shares are not mutually exclusive.

Next Steps
Where to take this from here
This page reports counts and classes from one search string. Turning that into a filing or freedom-to-operate view takes more targeted work.
Narrow the search string
A 40-family pool this size is sensitive to exactly which terms were used. Running adjacent phrasing or narrower disease terms in Eureka can show whether the same names and classes hold up, or whether this set is mostly an artefact of the terms chosen.
Refine this search in Eureka →Pull the granted claims directly
Neither an abstract nor a family count establishes what a granted claim covers. For any record here that matters to a filing decision, read the claim set itself before drawing a scope conclusion.

FAQ
Common questions about this dataset
This search returned 140 published records, which de-duplicate to 40 simple patent families once the same invention filed in multiple countries is collapsed to one. The search string carries no date limit, so this reflects every matching record the terms return rather than a chosen period. Because the terms used (microarray plus classification or diagnostic-signature language tied to disease or tumor) are specific, a differently worded search could return a different count.
Among the 25 listed filers, The Board of Trustees of the Univ of Arkansas is named on the most simple patent families: 6 of 40, a 15.0% share. That figure describes filing volume in this dataset only; it says nothing about claim scope, validity or commercial value, and filer names are not rolled up to corporate group, so related-looking entities are not combined into one total. 21 of the 25 listed filers hold 2 or fewer families each.
Published records in this set run from 2007 (24 records) to a peak of 27 in 2020, counted by earliest filing year. Years from 2022 onward are still filling in, because a filing only becomes visible once it publishes, which can take up to 30 months for applications entering national phase. No growth rate or trajectory can be read from this chart; treat the incomplete recent years as understated rather than as a decline.
C12Q (measuring and testing involving enzymes or DNA) is the subclass most frequently present, appearing on 33 of the 40 simple patent families (82.5%). G01N (material analysis and testing) follows at 57.5%, with G06F (electric digital data processing), G16B (bioinformatics) and C12N (microorganisms and genetic engineering) also present. A single family can carry several IPC classes, so these percentages add to more than 100% and should not be treated as a partition of the dataset.
No. The underlying set is 40 simple patent families, a small pool by any measure, and the filer list itself is capped at 25 names with individual inventors removed from that list (though still counted in the totals). Absence of a name, class or branch here is at least as likely to reflect the search terms used as any real gap in filing activity, so this page should be treated as a starting point for a more targeted search rather than a complete map.

Every answer comes back with patent numbers you can open.
How this page was built, and what the numbers do and do not mean
Search. Every figure on this page comes from one Patsnap search, run once and not edited afterwards. This is the exact search string:
TAC:(("gene expression microarray" OR "DNA microarray") AND (classification OR "diagnostic signature") AND (disease OR tumor))Reading the field codes: TAC searches the title, abstract and claims of each record, not the full description. The search string sets no date limit, so the scope is every matching record in the database regardless of when it was filed. It is not restricted to recent years. How this string was built matters for how far the counts can be pushed. It was generated in batch from a topic list rather than hand-crafted for this page, and the result set is not manually screened. A keyword search over title, abstract and claims both over-captures (unrelated filings that happen to use the same words) and under-captures (the same invention written in different words). This page cannot measure either effect, so read every figure here as what this particular string returned, not as what exists in the field. One subclass (C12Q) carries 82.5% of the patent families, so this search returned a classification-tight set.
What is being counted. Two different units appear on this page and they are not interchangeable. The filer list and the technology split are counted in simple (DOCDB) patent families: one invention counts once however many countries it was filed in. The total, the jurisdiction split and the filing-year chart are counted in published records: the same invention counts once per publication. For this search that is 140 records and 40 families. Record counts reward filing in many jurisdictions; family counts do not. Shares are only ever taken against a denominator in the same unit, and each one names it.
Who the filers are. Names come from Patsnap's standardised assignee field, as recorded on the documents themselves. They are not rolled up to corporate group: a parent and its subsidiaries appear as separate entries, and a portfolio acquired from another company stays under the name on the document unless the assignment is reflected there. This list is meant to carry organisations, not people. Filings held by a named individual are identified by matching the assignee against the inventors on the same search, and, for names written in Chinese, Japanese or Korean characters, by the name carrying no organisational suffix; those are removed from the list (33 of them here). Neither test is exhaustive: the inventor list it matches against is itself capped, and a personal name written in Latin script with no organisational wording in it cannot be told apart from a short company name by rule. So an individually held filing can still appear in the list. Those filings stay inside every total and share on this page either way, so the listed entries can add up to less than the total. A record shown in full further down still names its assignee exactly as the patent office records it, including where that is a person: that name is how the record is identified and checked. What is left out of the ranking is people as ranked entries, not people as cited sources. The table shows the top 25 of the 25 filers returned, ordered by count alone; the data endpoint returns at most 100 entities, so even that 25 is not every filer. One patent family can name several filers and each is counted separately, so these rows are not slices of a divided whole: adding them together over-counts, and this page deliberately publishes no combined "top five" share for that reason. See every filer, individuals included
Dates. The year chart counts by earliest filing year, not publication year. A filing only becomes visible once it publishes: roughly 18 months for most routes, and up to 30 months where a PCT application enters national phase. Measured across these pages, the year four back from today still holds only about 89% of its eventual count. 2022 onwards are therefore shaded on the chart as still filling in. The data behind this page was retrieved on 2026-10-27.
Legal status. "In force" counts documents whose legal status at retrieval was granted and maintained (22 of 140). Everything else is pending, withdrawn, refused, lapsed or not determinable, and those states are not broken out here because the underlying codes do not separate them cleanly. Legal status changes continuously and is reported per document, not per family. Get the status breakdown in Eureka
Classification. The technology split uses IPC subclasses (four characters, for example H01M). A single record usually carries several, so the shares add up to more than 100% and a record can appear in more than one bar. Subclass is a coarse grouping; it describes the field a record was classified into, not what the claims cover. Break the classes down to subgroup level
Who wrote the words. The tables, charts, counts, shares and patent numbers on this page are produced directly from the search result by a program; none of them are written or estimated by a language model. The surrounding prose, headings, FAQ answers and the answers in the question panel are drafted by a language model that is given those same figures and is not permitted to introduce others. Prose can still mis-describe a correct figure, so where the two disagree, the tables and charts are the record.
Disclaimer. This page is generated from Patsnap Eureka data drawn from a limited snapshot of global patent and scientific-literature records, and is provided for general information and reference only.
Patent data carries limitations that apply to every figure above. Recent filings are under-counted, because an application is not public until roughly 18 months after filing and database loading adds further delay. The search string defines and constrains everything shown: records that use different terminology, or that sit outside the fields searched, are absent and cannot be counted. Applicant names, classification codes, legal-status codes and citation records are taken as recorded and may contain errors, duplicates, omissions or stale entries. Ordering by volume is not a measure of quality, scope, enforceability or commercial value, and a larger portfolio is not a stronger one. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing on this page constitutes an exhaustive prior-art, novelty, freedom-to-operate, validity or infringement search, nor does it constitute legal, financial, investment, or professional advice, and it should not be relied upon as such. No attorney-client relationship is created by it. Any patent, commercial, or strategic decision should be verified independently against the primary records and reviewed with qualified patent, legal, and domain professionals. Patsnap makes no warranties, express or implied, as to the accuracy, completeness, or fitness for any particular purpose of the information presented.
The question panel. The answers behind the suggested questions on this page were written when the page was generated, not in response to your click. The progress steps that play before an answer appears are an animation of how that analysis was done; nothing is being searched or computed at that moment. Typing your own question instead opens Patsnap Eureka, which does run it live.
Machine translation. Assignee and organisation names originally recorded in Chinese, Japanese or Korean have been rendered into English by an AI translation step so that the tables stay readable. These renderings are best-effort and may not match a company's registered English name; the original name is what the underlying patent record carries, and it is what any Eureka query launched from this page uses.
