For even more details, please read the F.A.Q.

1 – Cloem® core technology comprises core algorithms encoding proven industry drafting practices, e.g. advanced handling of antecedences, hardcoding and exhaustion of the claim tree, handling of time in claims, method steps combinatorics, handling of claims' categories and intermediate generalizations, etc

2 – Trusted timestamping (and other undisclosed techniques, including trustless timestamping e.g. using the Bitcoin Blockchain). Free Cloems™ are not timestamped. Paid Cloems™ are timestamped.

3 – Publication is always optional.

"Private Cloems™" (unpublished, private index, protected access): a) texts are not published online: they remain private, i.e. confidential; b) private variants are not in the public index c) access is protected i.e. access rights are required to read contents and transport is encrypted over SSL EV (highest standard available).

"Public Cloems™" (published, public index, unprotected access): if you decide so, variants can be published. In order to publish variants, you are required to subscribe to the paid plan. By paying, you can publish variants any time you want.

4 – Public (published) cloems are searchable by anyone; private (unpublished) cloems are technically protected (encryption and access control lists) and searchable only by the corresponding user.

5 – Each cloem is associated with a unique and permanent (or quasi-permanent) web address (URL or QR code). Paid Cloems™ are each associated with a unique address, free Cloems™ are not.

6 - Free Cloems™ are hosted during a period of 60 days. After 60 days, variants are deleted from our servers. Paid Cloems™ are hosted for 7 (seven) years, as private and/or public texts, at your choice. Renewals for another period of 7 years are reminded by email alerts and cost the same price than the initial plan. If not renewed, variants are deleted from our servers.

7 - Cloems are tentatively grammatical, i.e. the vast majority of texts will be grammatical (but not all).

8 – Contributions of man and machine are deeply intermingled. As our clients can tightly control the vocabulary handled in variants, we claim that variants are of high semantic quality. About inventorship: in our view, users provides the lexical directions and the seeds of the invention with base claims or initial texts/definitions; our algorithms get the grammar right and explore the combinatorial space at best by suggesting and selecting words. As a result, a "beam" of inventions are created, which deserve the same attention than any other text or enabling disclosure (if applicable).

9 – An optional creation "wizard" let you elaborate your initial text, by selecting and further adapting a patent claim. Alternatively, you can paste standard patent claims up to entire claim tres.

10 – Modifications brought to the grammar of the initial text or claims is a complex topic; in short, clauses (e.g. relatives) can be added or deleted, the length of the claims can be varied, etc. By modulating the changes brought to the grammar, in combination with the vocabulary being used in claims, some degrees of control can enable to get "focused" or "wide" (or "balanced") textual variants.

11 – Cloem selects and injects vocabulary in variants with extreme care, based on intensive computations performed on the entire patent corpus representing millions of documents and based on our sophisticated legal model encoding industry and private practice drafting techniques, Patent Examination Guidelines and Patent Case Law. You can choose to let Cloem choose the vocabulary for you. But you can also control the vocabulary to be injected in variants. You can decide to manage alone the vocabulary you want to play with (for example if you want to avoid auto-collisions when creating prior art). Intermediary situations are also possible, by reviewing our suggestions, etc.

12 – Additional keywords can be optionally submitted in order to provide further lexical directions (e.g. by providing the patent specification/description or words thereof). Each provided keyword helps us bridging with other silos of words. Share your intuitions and let us do the rest!

13 – DBpedia (scientific and technical articles of Wikipedia), Wordnet and other sources can be used.

14 – Our dictionaries are proprietary and highly specialized for patents. They are derived from the analysis of 70 millions of patent documents, the entirety of technical articles of Wikipedia and a huge number of scientific articles (including handbooks and other sources representative of the Common General Knowledge of te skilled person). Definitions, synonyms, hyponyms, hyperonyms, meronyms, holonyms or even antonyms of words can be used. As an example, the definition of a term can be injected in order to desambiguate some variants (clarity).

15 – Cloem has extensively studied the IPC patent classification. Some controls on the vocabulary are opened to our users. Currently, three levels of granularity are accessible: subclass e.g. G06F, group e.g. G06F17 and subgroup e.g. G06F17/30. By mixing-up patent classes, you can create hybrid inventions (e.g. cross-fertilizing A61M with G06F).

16 – Common General Knowledge is derived from reference books, manuals, encyclopedias and the like (corresponding to legal criteria). Our dictionaries are also derived from a massive number of scientific publications as well from the patent literature (e.g. essential patents or key patents, for example those of recent and important litigation). Our vocabulary sources include "claim construction" dictionaries (e.g. definitions and meaning of words in view of past prosecution or litigation). Cloem has also developed a proprietary implementation of TRIZ, which is now part of our dictionaries and transformation rules.
