Patent search · run, not just typed
The engines hold the patents.
This desk runs the search.
Google Patents, Espacenet, The Lens and the USPTO’s own search already hold nearly every patent on earth. What they do not do is the work: restating the invention, mapping its concepts, writing one strategy correctly in each engine’s dialect, reading the records, and keeping an honest note of what was not searched. This desk does that work, keyless, in your browser.
It never says “novel”, “invalid” or “clear to operate”. Every patent number on this page comes from your own input or from a record fetched while you watch.
The gazette
Granted this week, as the offices publish them.
The USPTO issues its patents every Tuesday and the EPO publishes its grants every Wednesday. This is the newest issue of each, read when you open it, with every grant’s own timeline — when it was first claimed, filed, published and granted, and how long that took.
The newest issue loads when this band comes into view.
US grants come from SureChEMBL (EMBL-EBI), which loads the USPTO’s issue within about a day; the list of European grants from the EPO publication server’s weekly list, and each grant’s title, priority and publication dates from SureChEMBL. They reach you through this site’s own relay, which keeps each answer — the newest issue for an hour, its pages for six hours, a grant’s record for thirty days — so the upstreams are asked once, not once per visitor; if the relay is down, US grants are read from SureChEMBL directly. A grant is the office’s decision, not a verdict on validity.
The sheet
State the invention before you search for it.
The analyst’s method as a form: the problem, the numbered features, and for each feature the words an examiner might have used. You mark which features are conventional and which may be novel — nothing here guesses it.
Restatement & concept map
CPC picks
Each code is checked against the vendored CPC 2026.08 scheme; the reason is pre-filled with its official title for you to edit.
Scope
The compiler
One strategy. Five dialects. The traps named.
The sheet written four ways — broad landscape, keywords + CPC, claims-focused, tight closest art — each in the exact syntax of Google Patents, Espacenet, USPTO PPS, The Lens and PATENTSCOPE. Under every query, the specific ways that engine will surprise you with it.
Nothing compiled yet. Fill a feature in the sheet, then compile.
The reading room
Real records, read live.
Searched in the page against PubChem’s patent collection (NCBI; keyless, open to browsers). It has titles, abstracts, dates, parties, classifications, families and citations — and no claims text. The same words open in the big engines one click away.
No search run yet.
The record opens here. In the list, ↑ and ↓ move through the results.
The scheme
All of CPC, offline. Words to codes, no model.
Every one of the 254,314 symbols in CPC release 2026.08, served from this site. Paste a symbol to check and open it, or type ordinary words: WIPO’s catchword index answers first, then the words in the scheme’s own titles — and every suggestion shows what it matched.
Browse
The scheme loads when you reach it.
Words → codes
Type words above to see which codes hold them.
Text in {braces} is CPC’s own addition to an IPC title. Dots are the scheme’s indentation: each dot is one level below the main group.
The log
What was searched, when — and what was not.
Every query compiled, every engine opened, every search run here with its live count, every record read: stamped as it happens. The list of what this search missed is built from what the log shows was not done. A search is a link: the whole sheet travels in it, and nothing is kept on a server.
This session
What this search missed
“New since your last visit” is remembered on this device only, in this browser. There is no account and no e-mail alert.
Method
The sources, and what they do not give.
Records: PubChem, browser-direct
The in-page search and every record come from PubChem’s patent collection at the U.S. National Library of Medicine, fetched straight from your browser with no key and no relay: one request at a time, at least two seconds apart, and when PubChem says it is busy the desk waits as long as it is told. The search uses the backend of PubChem’s own website, which is not a documented API. The collection has no claims text.
Engines: linked, never fetched
Google Patents, Espacenet, USPTO Patent Public Search, The Lens and WIPO PATENTSCOPE are reached only by deep links that open in your browser. Every operator the compiler writes comes from that engine’s own help text; where an operator could not be confirmed, the nearest confirmed form is used and a trap says so. Each number link carries how far it was checked.
Classification: the whole CPC, here
CPC release 2026.08 (EPO and USPTO) and WIPO’s IPC catchword index (2026.01) are served from this site as a static pack, so the scheme works with no network call to anyone else. Suggestions come only from those texts and say which catchword or title words they matched.
This week’s grants: two keyless lists
THE GAZETTE reads the USPTO’s Tuesday issue through SureChEMBL
(EMBL-EBI), a public API that mirrors it within about a day, and the EPO’s
Wednesday grants from the EPO publication server’s weekly list. Both pass
through gazette.php on this site, which caches each answer and asks
upstream one request at a time; if it cannot be reached, US grants are read from
SureChEMBL directly. Each grant’s title, priority and publication dates come
from its SureChEMBL record; the dates are the offices’ own. PubChem, the
reading room’s source, trails the offices by months, so a grant from this
week will usually not open there yet.
Keyless, and what a key would add
Everything on this page works with no key. Two free keys exist that would add legal status and EP claims text (EPO Open Patent Services) and the office’s own patent term adjustment (USPTO Open Data Portal); both would run through this site’s relay so no key reaches a browser. Neither is installed, so the bench’s term is a labelled estimate; THE GAZETTE prints the adjustment a new grant itself records.
Three refusals
It will not tell you anything is novel, invalid, expired or clear to operate: a search can show what it found, never what does not exist. It will not score risk or “understand” a claim: there is no model here, only the documents’ own words. And it will not invent a number: every patent number shown came from your input or a record fetched this visit.
Not legal advice
This is a working tool for running and recording a search. It is not a freedom-to-operate, validity or patentability opinion; for those, take the log to a registered patent attorney or agent.
