The Invention of Invention

This paper models an industrial revolution as a qualitative transition from a world where innovation is infrequent and haphazard to one where it is continuous and systematic. Pre-industrial innovation is treated as a social process where an individual's effectiveness as an innovator depends on the skills of other individuals in his social network. As technology improves, individuals invest more time in learning through social contact. This gradual increase in linkage formation leads to a sudden change in the size of knowledge networks from small, isolated clusters, to a large connected cluster spanning most of the economy, causing a sudden increase in the effectiveness of innovation - an industrial revolution. The predicted sequence of typical innovators - from gifted amateurs, to lucky amateurs, to professionals - is consistent with empirical evidence.Industrial revolution, social networks, innovation

Stress-resistant plants and their production

The present invention relates to plant genes involved in negative regulation of resistance to biotic and/or abiotic stress and uses thereof. More particularly, the present invention relates to plants comprising an inactivated MADS-box gene function, and having increased resistance to biotic and/or abiotic stress. The invention also relates to methods for producing modified plants having increased resistance to fungal, bacterial pathogens and/or to drought stress. In particular, the invention relates to methods for producing plants with inactivated MAD26 gene, or an ortholog thereof, and exhibiting resistance to biotic and/or abiotic stress. (Résumé d'auteur

Patent Clutter

Patent claims are supposed to clearly and succinctly describe the patented invention, and only the patented invention. This Article hypothesizes that a substantial amount of language in patent claims is in fact not about the core invention, which may contribute to well-documented problems with patent claims. I analyze the claims of 40,000 patents and applications, and document the proliferation of “clutter”—language in patent claims that is not about the invention. Although claims are supposed to be exclusively about the invention, clutter appears across industries and makes up approximately 25% of claim language. Patent clutter may contribute several major problems in patent law. Extensive clutter makes patent claims harder to search. Excessive language in patent claims may be the result of over-claiming—when patentees describe potential corollaries they do not possess—thereby making the patent so broad in scope as to be invalid. More generally, it strains the comprehensibility of patents and burdens the resources of patent examiners. After arguing that patent clutter may contribute to these various problems, this Article turns to reforms. Rejections based on prolix, lack of enablement, and lack of written description can be crafted to dispose of the worst offenders, and better algorithms and different litigation rules can allow the patent system to adapt (and even benefit from) the remaining uses of excess language. The Article additionally generates important theoretical insights. Claims are often thought of as entirely synonymous with the invention and all elements of the claim are thought to relate equally strongly to the invention. This Article suggests empirically that these assumptions do not hold in practice, and offers a framework for restructuring conceptions of the relationship between claims and the invention

Constraints on predicate invention

This chapter describes an inductive learning method that derives logic programs and invents predicates when needed. The basic idea is to form the least common anti-instance (LCA) of selected seed examples. If the LCA is too general it forms the starting poínt of a gneral-to-specific search which is guided by various constraints on argument dependencies and critical terms. A distinguishing feature of the method is its ability to introduce new predicates. Predicate invention involves three steps. First, the need for a new predicate is discovered and the arguments of the new predicate are determíned using the same constraints that guide the search. In the second step, instances of the new predicate are abductively inferred. These instances form the input for the last step where the definition of the new predicate is induced by recursively applying the method again. We also outline how such a system could be more tightly integrated with an abductive learning system

Phase Length Optical Phase-Locked-Loop Sensor

The invention is a device that provides a high resolution measurement of the change in optical phase length from the device optical system source to an optical reflector. The invention consists of a optical phase locked loop that uses a laser beam as a carrier of an intensity modulated energy source. The novelty of the invention appears to lie in the overall combination of elements which provide high resolution without loss of wide dynamic range. The invention does not depend on coherent reflection from a target, and thus can measure targets that do not have special preparation or corner reflectors. The use of carrier modulation achieves high resolution without the problems of high speed pulse duration systems. Thus the invention has the advantages of simplicity, low cost, and small size without sacrificing resolution
