The United States Patent &amp; Trademark Office (USPTO) routinely rejects claims as too broad, arguing that such claims cover more antibodies than the specification discloses, or that undue experimentation would be needed to determine whether an antibody reads on the claims. These heightened disclosure requirements increase laboratory costs to generate sufficient data for a \u00a7112(a)-proof specification.<\/p>\n<\/div>\n<p>  <!----> <!----> <!----><\/p>\n<div data-v-1c1aa57e=\"\">\n<h2 label=\"&lt;bsp-line&gt;&lt;b&gt;Written Description and Enablement Generally&lt;\/b&gt;&lt;\/bsp-line&gt;\"><b>Written Description and Enablement Generally<\/b><\/h2>\n<p>The legal standards for written description and enablement are well-established. To meet the written description requirement, the specification must convey with reasonable clarity that as of the filing date the inventor was in possession of the claimed invention. <i>See<\/i>, <i>Vas-Cath, Inc. v. Mahurkar<\/i>, 935 F.2d 1555, 1560 (Fed. Cir. 1991); <i>Ariad Pharm., Inc. v. Eli Lilly &amp; Co.<\/i>, 598 F.3d 1336, 1351 (Fed.

The enablement requirement is met if the specification would allow a person of ordinary skill in the art to make and use the claimed invention without undue experimentation. <i>See<\/i>, <i>Amgen, Inc. v.
