A method of placing a discrete value on an intellectual property asset through a series of associations and calculations that determine the proportional contribution of an intellectual property asset to the competitive advantage of a related product in a real market. The methodology of the present invention first associates the intellectual property asset with a related tangible asset that embodies the intellectual property asset. After a set of parameters that define the tangible asset are identified, the tangible asset is quantitatively compared to competing tangible assets in the marketplace to determine its overall competitive advantage relative to those competing assets. The contribution of the intellectual property asset to the average competitive advantage of the tangible asset in which it is embodied is calculated by first comparing the intellectual property asset to substitute intellectual property assets that are embodied in competing tangible assets and associated with the same parameter. Next, the intellectual property asset is compared to complementary intellectual property assets that are included in the same tangible asset and associated with the same parameter group. Based upon the proportional competitive advantage contribution of the intellectual property asset to the average competitive advantage of the tangible asset, a percentage of the tangible asset's present value is assigned to the intellectual property asset. The present invention can also be used for planning development of pre-market products, calculating the value of a license to a licensor and licensee, and selecting among alternative research and development investments.

A face mask assembly and method of assembling a face mask is provided for a patient that includes a face piece sized to fit over the patient's nose and mouth. The face mask assembly forms a mask chamber between the face piece and the patient's nose and mouth. An inhalation adapter is coupled to the face piece to deliver medication to the chamber. A filter housing is coupled to the face piece and includes a flange section that defines a passageway to connect the mask chamber and the flange section. A filter is positioned in the filter housing. A cover is coupled to the flange section and has an exhalation opening or vent to allow gases from the mask chamber to pass through the filter and escape from the passageway to the atmosphere. In a second embodiment, the filter housing is modified by providing a frame adjacent the bottom with a cross-shaped structure and a retainer button attached to the housing. A valve disc is provided between the retainer button and frame adapted to allow gases from the mask chamber around the valve disc towards the filter. When a patient inhales oxygen through the nasal portion, the valve disc moves towards the mask and partially covers a plurality of apertures to partially block additional air from entering the chamber. When a patient exhales contaminated oxygen, the valve disc moves towards the retainer button to allow a maximum amount of air through the apertures towards the filter.

A nanoporous catalytic membrane which displays several unique features including pores which can go through the entire thickness of the membrane. The membrane has a higher catalytic and product selectivity than conventional catalysts. Anodic aluminum oxide (AAO) membranes serve as the catalyst substrate. This substrate is then subjected to Atomic Layer Deposition (ALD), which allows the controlled narrowing of the pores from 40 nm to 10 nm in the substrate by deposition of a preparatory material. Subsequent deposition of a catalytic layer on the inner surfaces of the pores reduces pore sizes to less than 10 nm and allows for a higher degree of reaction selectivity. The small pore sizes allow control over which molecules enter the pores, and the flow-through feature can allow for partial oxidation of reactant species as opposed to complete oxidation. A nanoporous separation membrane, produced by ALD is also provided for use in gaseous and liquid separations. The membrane has a high flow rate of material with 100% selectivity.
