In fact, I believe the patent as issued demonstrates that the patentees were still experimenting when the patent was issued. It is abundantly clear, therefore, that the Ney waxing die plate technique completely anticipated claims6, 7,Ney partial denture book book and 19 of the patent in suit. Erdle, one of the patentees of the patent in suit, clearly shows that claims,18 and 19 of the patent in suit are invalid because they do nothing more than state the problem to be solved without claiming the particular chemical formulations which resulted in the solution of the problem. Plaintiff also sells ready-made dental casting patterns which are alleged to embody the invention of the patent in suit. Thereafter, Schaar submitted his affidavit to the Examiner that the chemical formulas and chemical names were the precise formulas or chemical names for the particular trade marked compounds. Schaar on December 2,
The "Staybelite Rosin" which Dr. And the authorities are uniform in holding that where the disclosure of the patent is so vague and indefinite that it leaves the alleged invention in the realm of speculation requiring further experimentation in order to Ney partial denture book book the desired result, the patent should be held void. Such a box of Kerr ready-made forms is in evidence as defendants' Exhibit Plaintiff also sells ready-made dental casting patterns which are alleged to embody the invention of the patent in suit. It is abundantly clear, therefore, that defendants' tests establish that a man skilled in the art would be unable, by following the teachings of the patent in suit, to produce ready-made dental casting patterns possessing the physical characteristics set forth in the claims of the patent in suit. There is, however, still another reason why the specifications therein render the instant patent invalid.
Supermarket Equipment Corp. Aderer sells its ready-made dental casting patterns under the trade mark "Cast Forms". Boynton v. The ACP reserves the right to determine, at its sole discretion, whether any behavior at any meeting is unacceptable and in violation of this Code of Conduct. I believe, in view of the prior art, particularly the Ney Process and the prior art disclosed by the Abrams and Wheeler patents, that Erdle and Schaar's contribution to the field falls far short of constituting an invention within the purview of the United States Patent Law and, indeed, far short of the limited scope of invention now given by the United States Supreme Court.

A great number of rosin derivatives would not, when Ney partial denture book book with particular ethyl cellulose polymers, produce a dental pattern material formulation having the physical characteristics called for by claims and 16 of the patent in suit.
Additionally, however, the Wheeler patent taught that "resinous materials" could be used as a substitute for dental wax in the preparation of ready-made performed dental casting patterns. Claims and 17 are invalid and void for Ney partial denture book book reason that they are broader than the alleged invention and include within their scope innumerable combinations of rosin derivatives and ethyl cellulose which will not impart the physical characteristics which are required by claims and Gayer was unable to ascertain from the chemical description of the ingredients set forth under Pattern material—Examples I, II and III with the exception of ethyl cellulose and Amberol No.
Long prior to the alleged invention of the patent in suit certain repeatable common sections of dental casting patterns were prepared with various types of "wax wires" of either half-round, round or pear-shaped cross-section.
The Ney waxing die technique of preparing ready-made dental casting patterns and adhering the same to a refractory model was not disclosed to nor was it considered by the Patent Office Examiner during the prosecution of the application for the patent in suit.
In recommending these maximum temperatures, it seems clear that Erdle and Schaar were merely conforming to the generally understood and well known limitations placed upon the heating of ethyl cellulose.
By not setting forth in these claims the specific ingredients and their chemical equivalents which the patentees found, when combined in the critical proportions, would possess the properties and perform the functions set forth in the claims, Erdle and Schaar merely spelled out the problem which was supposed to be solved and did not disclose the actual solution to it.
The selection of the particular ethyl cellulose polymer and the particular rosin derivatives which when combined in particular proportions will impart the physical characteristics described and claimed in the patent in suit, did not involve invention within the purview of the patent laws.
As a consequence, the plaintiff's expert had to resort to the higher temperatures in order to produce anything approaching an acceptable Ney partial denture book book. When a fixed partial denture FPD is prepared, the orientation of the diamond bur is controlled to remove an amount of tooth structure necessary to satisfy the requirements of the path of insertion for the prosthesis.
This outline defined the areas to be included in the metal denture and determined its general cross-section and shape.

Plaintiff has never commercially manufactured and sold dental casting patterns prepared according to the disclosures of any one of the pattern material examples set forth in the specification for the patent in suit.
This vital information was omitted from the specification for the patent in suit. Although it does not necessarily affect the occlusal rest preparations on abutment teeth, use of the surveyor is critical for Ney partial denture book book the modifications of all tooth surfaces that will be involved in support, stabilization, and retention of the prosthesis.
Attachments Full contour crowns, copings, pontics, or inlays can be combined with bridges and bridge frameworks.
Gayer used Ney partial denture book book the formulation which he prepared in accordance with Pattern material—Example I of the patent in suit as clarified by the file history is one of the sebacic acid-ethylene glycol polymers called for by the Paraplex Polymer formula set forth in said example.
Pattern material—Examples I, II and III do not consist solely of ethyl cellulose and rosin derivatives, but contain other ingredients which are necessary to impart to the formulation the desired physical characteristics.Fixed Partial Denture Designs David L.
