Struct PatentBiblio 

#[non_exhaustive]
pub struct PatentBiblio {
    pub title: String,

    pub applicants: Vec<String>,
    pub inventors: Vec<String>,

}

Bibliographic metadata for one patent. Returned by EpoClient::fetch_biblio.

All fields except title/abstract_text/classification/cpc_classifications are Option/empty when EPO did not supply them. The parser prefers the granted publication (kind starting with B) when EPO returns an application+granted pair for the same patent.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

title: String

English-language invention title, falling back to the first available language when no English variant is present.

abstract_text: String

Full English-language abstract body, extracted from the <abstract><p> shape. Empty when EPO didn’t include an abstract (some applications ship without one).

assignee: Option<String>

First applicant in epodoc format. Kept for backward compatibility; new callers should prefer applicants for the full list. Equivalent to applicants.first().cloned().

applicants: Vec<String>

All distinct epodoc-format applicants (or the original-format list as fallback). EPO often lists multiple — joint applicants, subsidiaries, translation variants — and each carries the country-code suffix ([NL], [US], …) when known.

inventors: Vec<String>

Inventors in epodoc format. Same fallback as applicants — original-format names are skipped when an epodoc entry exists.

filing_date: Option<String>

Application filing date (YYYY-MM-DD).

publication_date: Option<String>

Publication date (YYYY-MM-DD) of the chosen exchange-document. When EPO returns A1+B1 for the same patent, this is the B1 (granted) date.

priority_date: Option<String>

Earliest priority claim date (YYYY-MM-DD). For PCT applications this is usually the original national filing.

kind_code: Option<String>

Publication kind code: A1/A2 (application), B1/B2 (granted), T1/T2/T3 (translations), country-specific.

family_id: Option<String>

EPO @family-id. Pass to EpoClient::fetch_family callers if you want to skip a round-trip — same family-id always yields the same member list.

classification: Vec<String>

Full IPC codes (B28B1/29), de-duplicated across the classification-ipc and classifications-ipcr blocks. Not truncated to subclass.

cpc_classifications: Vec<String>

CPC codes from the structured patent-classifications block, de-duplicated across reporting offices (US/EP/IL/KR/CN can each classify the same patent with the same code).
