In addition to utiHty patents, some countries pubHsh patent documents under different or less stringent standards for patentabiHty and with shorter patent terms. For example, plant patents cover asexually reproduced plants. Design patents cover the decorative aspects of a product. UtiHty models and petty patents cover products with differences from the prior art that need not meet the nonobviousness standards set for utiHty patents.

Design Patents. Design patents are granted to individuals who have invented new, original and ornamental designs for an article of manufacture. A design patent has a total time limit for exclusive use by the inventor of 14 years. 

At this writing, we have designed and built a small production unit to test and demonstrate the CBI process in a continuous system. The equipment design (patent pending) incorporates mechanical simplicity and energy efficiency into a reliable,...

During the past ten years, no less than 34 major pyrolysis projects have been proposed, designed, patented, licensed, or built (see Table 8-2). Only one or two are operational today, arguably, none on a commercial basis. Technically, tire pyrolysis is feasible but financially, it is very questionable. This section reviews some of the highlights of the financial analysis of the process and products. 

Plant patents and design patents are separate statutory classes but are not here pertinent. 

Opposed Jet Mill Opposed jet mills are fluid-energy-driven mills that contain two or more jets aligned toward each other (see Fig. 21-71h). Different versions are on the market, based on a design patented by Willoughby (1917). In this type of jet mill, opposed gas... 

A patent can be enforceable from the time it is issued till it expires, not necessarily 20 years. New rules provide some guarantee that the enforceable term of a utility patent will be at least 17 years, and that some royalties may be collectable when a patent is published before it is issued. Design patents are only good for 14 years and only cover the ornamental appearance of the item, and not its structure or functionality. 

Bradford Particle Design patented another way to perform the SEDS. In this method, nitrogen was the antisolvent, while the substrate to be micronized was solubilized in CO2. Salicylic acid was processed by means of this approach (140) Table 4 provides additional examples (15,16,132-134,136, 137,141-156).
