The biggest feature and strength of PatentPia GoldenCompass is the organized and rich contents scheme related to keywords.
Keywords are the fastest and most intuitive way to characterize not only individual patents, but also patentsets. However, given a patentset, extracting and organizing keywords from that patentset is a daunting task. GoldenCompass provides a service scheme to extract, analyze, classify, cleanse (filter, etc.), visualize, download or report on keywords contained in patentsets corresponding to i) companies, ii) fields, iii) researchers, or iv) any combination thereof.

Using Apple as an example of a keyword extraction company, Myers Scott A. as an example of a keyword extraction researchers, and augmented reality as an example of a keyword of interest, we provide keyword contents utilizing PatentPia GoldenCompass. If you click on the chain (link) marks that are attached to each item in the above utilization map, the example page will open in a new window.
The content scope for extracting keywords from patents is the i) title, ii) abstract, and iii) claims of the patent. In special cases, we also extract from the description of the invention and patent drawings. Keywords are extracted from individual patents, and a keyword set corresponding to a patent set (SET), which is a collection of patents, is generated by combining the keywords extracted from individual patents.
In GoldenCompass, the source from which a keyword occurs is the patentset corresponding to a single item, such as i) company, ii) field, iii) researchers, or iv) a composite item, which is a combination of these. For item vs. patentset assignment/mapping, see the page "Item vs. Patentset Mapping".
A company is based on the entity that has rights to a patent, i.e., the right holder. A particular patent applied for by an applicant may be assigned to the current right holder. In this case, the keywords contained in that patent are assigned/mapped to the current right holder, not the applicant.
The fields include i) technology, ii) products-parts, iii) products-materials, iv) patent classification (CPC/IPC, etc.), v) concepts (coming soon), and vi) keywords.
For each field, such as a technical field or patent classification (e.g., a specific CPC classification code), there is a corresponding patent set. When there is a specific keyword (e.g., "augmented reality"), there is a patent set containing this keyword, and there are many other keywords that co-occur with "augmented reality" in this patent set. Therefore, the keyword (e.g., "augmented reality") itself is also a source of other keywords (e.g., (e.g., keywords that co-occur with "augmented reality").
(Note) Patent sets that are assigned to/respond to/mapped to a patent classification are processed using the main patent classification contained in the patent, i.e., only patents with a particular patent classification as the main patent classification are used as patent sets that are assigned to/respond to/mapped to that patent classification. On the other hand, for patent classifications that cannot be the main patent classification (e.g., CPC 2000 series or Y section), we use the patentset that is assigned/responds/mapped to the patents with that patent classification used as the sub patent classification. For more information about patent classifications, please refer to the "Patent Classification" page.
The inventor is the entity that made the invention for a patent. The inventor does not change even if the patent is assigned. If a particular patent was invented by multiple inventors, the keywords extracted from the patent are assigned/mapped to all of them.
