DPMAregister is the official register and publication database of the German Patent and Trade Mark Office. It carries the office’s registers for patents, utility models, topographies and supplementary protection certificates, for trade marks and geographical indications, and for designs, each with its own search interface.
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.
Open The overview page and the basic search interfaces for patents, trade marks and designs were all retrieved anonymously without any credential. Rate limiting was not probed and no CAPTCHA was encountered, but absence was not established, so no CAPTCHA claim is made either way.

Assessment
Strengths
It is the German office’s own register database, so it is the authoritative source for the status of a German industrial property right rather than a commercial copy of it.
Three separate rights families each have their own dedicated search entry point, which keeps patents, trade marks and designs from being conflated in one undifferentiated result set.
Searching is free and worked anonymously, with no account required to reach any of the basic search interfaces.
Limitations
Only the German-language register excerpt is legally binding. The office labels its English output a non-binding translation.
It is a register of rights. It does not record whether a right is being used, whether it is commercially significant, or whether it is being disputed outside the register.
The office’s main site refused automated requests behind a JavaScript interstitial, so background documentation had to be read from the register host itself.

Best for
Checking the status, owner and filing history of a German patent, utility model, trade mark or registered design.
Establishing whether a mark or design is already registered in Germany before filing.
Not recommended for
Company verification. This register records industrial property rights, not the existence or officers of a business.
Relying on the English interface for a legally binding statement, because the office treats only the German register excerpt as binding.

Common mistakes
No common mistakes recorded yet.
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.
