The official nationwide directory of patent attorneys admitted in Germany, kept by the Patentanwaltskammer. It covers individual patent attorneys, in-house patent attorneys and professional practice companies, and admission is required to practise rather than only to use the title.
Domain Rating is a dated Ahrefs snapshot of domain authority. PetroHrys Score is an independent editorial assessment of the directory’s practical business value. They are separate measurements and are never combined. Domain Rating values are dated historical Ahrefs snapshots. Domain Rating is a dated historical measurement of the shared domain, not an assessment of this individual registry page. New measurements are not collected because the Research Center does not depend on mandatory authenticated APIs. Where several registries are published on one measured domain they repeat that domain’s single dated snapshot rather than each carrying a figure of its own. Domain Rating is a third-party metric produced by their respective providers, not by PetroHrys.com. Each recorded value carries its provider and the date it was measured, and describes the domain that was measured rather than one page on it. No source has been consulted for authority score, estimated traffic and referring domains, so they are not published for any record.
Partly open The search mask was served anonymously with no credential, with fields for salutation, title, name, place and company, so login is recorded as not required. No query was executed, so result content and any limits were not observed and stay null.

Assessment
Strengths
The chamber describes it as an electronic directory of all patent attorneys admitted in Germany, maintained on a daily basis.
It covers professional practice companies under sections 52f and 159 of the Patent Attorney Regulations, so firms are searchable and not only individuals.
It reaches European patent attorneys established in Germany and patent attorneys from other states, each shown with the professional title of their home state.
Limitations
Admission is required to practise as a patent attorney, so this is a licence register — but an entry is not a statement about experience in any technical field or trade.
It records individuals and practice companies together, so a result must be read carefully to know which kind of entry has been returned.
The chamber keeps the directory and admits its members; it does not supervise the conduct of any individual mandate.
The application issues a session-specific address on entry, so a copied link is not a durable citation and a reader should return through the register’s own domain.
Absence does not establish that a person never practised. Admission can end, and the directory shows who is admitted now rather than a history of the profession.
No search was executed during verification, so result content and any limits were not observed and none is asserted.

Best for
Checking that a named patent attorney is admitted in Germany before instructing them.
Confirming that a patent practice company is admitted under the Patent Attorney Regulations.
Not recommended for
Choosing an attorney by technical field. The directory records admission, not expertise in a technology.
Assuming coverage of European Patent Attorneys generally. Only those established in Germany under the applicable provisions appear.

Establishing required submission assets requires submitting a listing and observing the result. That has not been done for any directory in this dataset, so it is not published rather than estimated.

The PetroHrys Score is a first-party editorial assessment, not a third-party
authority metric. It is the weighted sum of the ten factors above, divided by ten, so the number
on this page is reproducible from the values shown. Each factor is scored from 0 to 10 by a human reviewer and weighted as shown. The definitions describe what was weighed, not a rubric: no threshold or formula maps a directory onto a value, and two reviewers could reach different numbers. The score is reproducible from the factors shown on every record, but it is an editorial judgement, not a measurement.
