What was search like?
• Reading the patent
application• Assessing the relevant
technical fields: classification
symbols.• Retrieving the relevant
“groups” from “pigeon hole”
shelves.• Browsing through the groups.• Selecting the best
documents to be cited in the
search report.

What it meant for Documentation
•Maintenance of a huge classified
paper collection:• Acquiring paper collections.• Maintaining and classifying
them.
•Maintenance of an up-to-date
classification scheme:• Classifying all incoming
documents.• Maintaining a classification

A method of forming an adhesive force includes
removing a seta from a living specimen, attaching the
seta to a substrate, and applying the seta to a surface
so as to establish an adhesive force between the
substrate and the surface. The seta is applied to the
surface with a force perpendicular to the surface. The
seta is then pulled with a force parallel to the surface
so as to preload the adhesive force of the seta.

Derwent
AB - WO200149776 NOVELTY - An adhesive force is formed by removing seta from living specimen. The seta is attached to a substrate and applied to a surface to establish an adhesive force between substrate and surface.
- DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (A) a method of fabricating an adhesive microstructure comprising fabricating an array of shafts and
forming spatula on the array of shafts; and (B) a fabricated microstructure comprising a shaft and an array of spatula formed at an end of the shaft. Each spatula includes curved segment of a sphere at spatula terminal end. The shaft is less than 500 mu m long, and has a diameter of 0.01-0.1 times its length. The array of spatula is less than 10 mu m wide.
- USE - The method is for forming an adhesive force for use in e.g., micro-manufacturing, micro-manipulation, and microsurgery applications. The adhesive force can also be used in manipulating retinal prosthesis implants, and pick and place of silicon wafer or disk drive components. It can also be used as clutch mechanism in micro-machines. It can also be used in insect trapping, tape, robot feet or treads, glove/pads for climbing, gripping e.g., clean room processing tools, micro-optical manipulation, micro-brooms, micro-vacuums, flake removal from wafers, optical removal of individual particles, climbing, throwing, and sticker toys, press-on fingernails, silent fasteners, substrate to prevent adhesion on specific locations, broom to clean disk drive, post-it notes, band aids, semiconductor transport, and clothes fasteners.
- ADVANTAGE - The formed adhesive force is greater than the cumulative force of the applying and the pulling steps of the forming method. The
removing step is analogous to cutting hair, thus allowing the gecko to harmlessly regenerate its seta. The seta is easily harvested without sacrificing the living specimen.
