Patents by Inventor Peter C. Richardson

Peter C. Richardson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8052987
    Abstract: The invention relates to bisphosphonates, in particular more potent N-bisphosphonates such as zoledronic acid and derivatives, and to methods of treatment using bisphosphonates. These bisphosphonates are used with satisfactory results for prolonged inhibition of bone resorption in conditions of abnormally increased bone turnover, e.g. osteoporosis, by intermittent administration, the periods between bisphosphonate administrations are longer than was previously considered appropriate, e.g. a dosing interval of at least about 6 months or less frequently.
    Type: Grant
    Filed: June 18, 2001
    Date of Patent: November 8, 2011
    Assignee: Novartis Pharmaceuticals Corporation
    Inventors: Zebulun D. Horowitz, Peter C. Richardson, Ulrich Trechsel

  • Patent number: 3962322
    Abstract: An improved process for the conversion of an unsaturated aldehyde (such as acrolein) to the corresponding unsaturated carboxylic acid (such as acrylic acid) is disclosed. The improved process comprises reacting in the gas phase at a temperature sufficient to accomplish the desired reaction of the aldehyde with oxygen in the presence of unagglomerated particles of a supported catalyst having the empirical formula Mo.sub.a V.sub.b W.sub.c Mn.sub.d O.sub.e, the atomic ratio of Mo:V:W:Mn:O being such that when a is 12, b is 0.5 to 12, c is 0.1 to 6, d is 0.5 to 20 and e is 37 to 94, the catalytic metals being supported on porous silica particles having a surface area of from about 25 to about 350 m.sup.2 /gm and a porosity of from about 0.2 to about 1.0 cc/gm whereby essentially all of the catalytic metals are contained on the surfaces of the particles.

  • Patent number: 3939096
    Abstract: An improved catalyst for use in a process for the vapor phase conversion of an unsaturated aldehyde (such as acrolein) to the corresponding unsaturated carboxylic acid (such as acrylic acid) is disclosed. The improved catalyst comprises an unagglomerated, supported catalyst having the empirical formula Mo.sub.a V.sub.b W.sub.c Mn.sub.d O.sub.e, the atomic ratio of Mo:V:W:Mn:O being such that when a is 12, b is 0.5 to 12, c is 0.1 to 6, d is 0.5 to 20 and e is 37 to 94, supported on porous silica particles having a surface area of from about 25 to about 350 m.sup.2 /gm and a porosity of from about 0.2 to about 1.0 cc/gm, whereby essentially all of the catalytic metals is contained on the surfaces of the particles.
