# Recipe: Invalidity Analysis
Build a prior-art invalidity case against a target patent, claim by claim.
## Step 1: Target Intake — Fix the Critical Date
```bash
flowleap --json summary <target-patent> # biblio, legal status, family, term
flowleap --json ops claims <target-patent>
flowleap --json timeline <target-patent> # filing/priority events
```
The earliest priority date is the critical date: prior art must predate it
(mind grace periods and jurisdiction differences). Record it before searching.
## Step 2: Decompose the Asserted Claims
Save each independent claim to a file, then:
```bash
flowleap analyze-claim --file claim1.txt --focus elements
flowleap analyze-claim --file claim1.txt --focus search # suggested queries
```
Every element in the list must be found in the art — track them as a checklist.
## Step 3: Hunt Prior Art Per Element Combination
```bash
# Patent art, both databases
flowleap patent build-query "<element combination in plain language>" --focus broad --allow-external-processing
flowleap --json patent search --query "<generated CQL>" --limit 30
flowleap --json uspto search --query "<generated CQL>" --limit 30 # ODP Lucene syntax
# Non-patent art — bound by the critical date
flowleap --json academic search "<element keywords>" --to-year <priority-year> --limit 20
flowleap --json npl "<element keywords>" --to-year <priority-year> --limit 20
```
## Step 4: Mine the Prosecution Record
```bash
flowleap --json citation search <applicat
