The listing of patents published by the United States Patent Office was searched for polymorph and solvatomorph patents using the keywords polymorph(s), polymorphic, solvate(s), hydrate(s), crystal form(s), and crystal modification, and the following patents issued during 2005 were returned using these keywords. 

Essentially, there are two kinds of affidavits—those designed to establish conception and reduction to practice prior to the effective date of a cited reference (Rule 131) and the affidavit under Rule 132 to show the value of the invention in the light of the prior art. These affidavits are referred to by the rule numbers in accordance with the Rules of Practice of the United States Patent Office. ...

Patent specifications are published in a form similar to ours and the abstracts are published in the Bulletin of Inventions, ByuUleten Izobretenii, which is roughly comparable to the Official Gazette, United States Patent Office (2). 

Drawings are required in patents "whenever the nature of the case admits of it (Rule 81, Rules of Practice of the United States Patent Office in patent cases). "The drawing must show every feature of the invention specified in the claims (Rule 83). Similarly, scientific papers include drawings illustrating new relationships, or novel components or arrangements of apparatus. 

The United States Patent Office has a numerical set of Soviet patents numbered 1 to 3500 (1924 to 1927) and starting again with 116,000 (1958). The first two patents were chemical in nature, the first on a furnace for the continuous preparation of sodium sulfide and the second on water purification IChem. Abstracts, 27, 3787, 3763 (1933)]. The patents issued since 1927 have not been available information concerning some of the chemical patents has been published in Chemical Abstracts based on abstracts given in the Russian Patent Office periodical. The latter is a monthly publication containing abridgments of issued patents, lists of applications, utility models, information on trade-marks. Patent Office notices, and reviews of current technical literature. A superb summary of the patent law, its administration, and the availability of abstracts was presented recently by Hoseh (248). 

Over a century ago, C. M. Keller, examiner at the United States Patent Office, recognized the potentialities for progress in foreign as well as domestic inventions, when he wrote ( Report of the Commissioner of Patents for the Year 1844, by Henry L. Ellsworth, 28th Congress, 2nd Session Senate 75, page 464) ... 

After the United States patents have been examined, the foreign patent art still remains to be covered. Here again the only sets of classified foreign patents available to the public are to be found in the Scientific Library of the United States Patent Office, which maintains both numerical and classified sets of patents from... 

The patent phase of the work is handled somewhat differently but in an equally efficient manner. The head of the Patent Section of Gulf Research Development Co. examines each copy of the Official Gazette of the United States Patent Office for patents of interest. He then obtains copies of the patents, roughly classifies them, and sends them to qualified persons at the research laboratories for abstracting. Since each man receives only patents which directly pertain to his specialty, the abstracting involves a minimum of mental effort—hence time. The patents, accompanied by copies of the abstracts, are then sent to Mellon Institute for classification and filing in a manner analogous to the way in which the literature is handled. 

Some indication of the importance of British chemical patents at that period is given by the comment of the United States Patent Office examiner in that field, Charles G. Page, when he stated in 1844 ( Report of the Commissioner of Patents for the year 1843, 28th Congress, 1st session, Doc. No. 177, page 314) ... 

The classification manual, which was translated by Lovett of the United States Patent Office 175), is the second edition (1910) of the Gruppeneinteilung der Patent-klassen 172). The companion subj ect index (key-word title index), which was translated by Kuhlmann of the United States Patent Office 172) is the 1914 edition of the Stich-worterverzeichnis, alphabetische Zusammenstellung 178). The bulky United States classification manual 181) and its index are wallflowers in comparison with these handy attractive guides. The present discussion is based mainly on the 1910 176) edition, because most of the classified set at the Patent Office is bound in accordance with it.

Classification, as exemplified by the system employed by the United States Patent Office, groups together in fixed compartments items having certain common features. In the Patent Office classification, the subject matter of the patent is analyzed by the classifier in terms of the features on which the classification system is built. Terminology ranging from the highly generic, e.g., carbon compounds, toys, medicines, poisons, and... 

The United States Patent Office began its interest in agricultural matters in the 1830s. Eventually, an Agricultural Division was established in the Patent Office, and a chemical laboratory was funded in that Division. 

Second to the United States Patent Office, the largest database is accessed through the European Patent Office, where one should conduct a similar classification search as suggested previously for the United States Patent and Trademark Office (2). The World Intellectual Property Organization (3) offers many useful features including complete details of the Patent Cooperative Treaty and its gazette. The Canadian Patent Office can be reached at the website mentioned in Ref. 4. 

Patents contain much information concerning fabricating methods and machinery. The United States Patent Office has established classifications for various kinds of equipment. This classification list is available in most libraries and can be obtained from the United States Patent Office. 

The Patent Gazette (29) is issued weekly by the United States Patent Office, and it may be studied for abstracts of new patents. Also, various current magazines publish patent digests in their editorial pages (27) and (28) list new patents as a regular editorial feature. These digests are often several weeks old, but they are a good source of information. 

Foreign patents may be found at the United States Patent Office, although they are not classified in the same fashion as the United States patents are.
