It is essential for patent information professionals to select the best tools available for their project to avoid missing critical information. However, decision-makers often struggle with a lack of reliable background information and industry context when making subscription choices. This article describes a free wiki-based web resource, Intellogist, which provides objective information and expert opinions about patent and prior art search tools, as well as a forum for community discussion of these tools. In addition, the article will focus on the criteria used to produce the in-depth system reviews and comparisons offered on the site. Intellogist's increasing membership, traffic, and community participation statistics are also discussed. © 2010 Elsevier Ltd.

We present a study to probe the formation of localized aromatic sextets and their effects on the charge transport properties in polymers with acene cores. Bithiophene-acene copolymers containing benzene, naphthalene, or anthracene as acene cores were synthesized using Yamamoto polymerization. Drop-casted polymer films were chemically doped and analyzed using high frequency saturation transfer EPR (HF ST-EPR), a method which has proven useful in the study of conducting polymers. The spin-spin and spin-lattice relaxation times were determined for these polymers at low temperatures (4 to 20 K) and used to obtain inter- and intrachain spin diffusion rates and conductivities. Similar interchain spin diffusion rates were seen across all polymer systems; however, anthracene containing polymer poly(hexylTTATT) was found to have the largest intrachain spin diffusion rate. The poly(hexylTTATT) intrachain spin diffusion rate may be artificially high if the anthracene ring restricts the diffusion of spin to the hexylated quaterthiophene segment in poly(hexylTTATT) whereas the spins diffuse through the acene cores in the benzene and naphthalene derivatives. Alternatively, as both the spin diffusion rates and conductivities vary unpredictably with temperature, it is possible that the π-electron localization previously seen in the anthracene core could be relieved at lower temperatures. © 2016 American Chemical Society.

This paper presents a design guideline for a piezoelectric actuated check valve diaphragm micropump for microfluidic applications. Diaphragm average displacement was adopted in analyzing a piezoelectrically actuated diaphragm. For the first time, the relationship between the stroke volume and backpressure of a check valve diaphragm micropump were simulated with a Finite Element Analysis (FEA) tool. The simulated results reasonably agreed to the experimental results of the micropump. © 2011 Elsevier B.V. All rights reserved.


A tool for navigating composite documents composed of multiple component documents. The tool allows a user to enter a composite document identification number, and thereafter have access to each component document within the composite document. The user can view, compare and display comparisons of the component documents, including versions of component documents. A graphical user interface is provided that prompts the user for required information and provides the user with many useful views for analyzing the component documents. In an embodiment, the composite document is the file history for a patent and the component documents are amendments, including application claims, and other papers found in a file history, such as the patent application, as originally filed, and the resulting patent. One feature of the tool allows the user to select a claim and have all versions of the claim displayed for easy review and analysis. This displaying ability allows the user to follow the progression of the claims during prosecution. The tool emphasizes all changes made to the claims, and provides annotations and links directly to the corresponding amending document.

A gathering, manipulating and analyzing tool for reviewing, displaying and creating reports on composite documents, wherein a composite document is made up of multiple component documents. The present method allows for entry and editing of metadata associated with component documents of the composite document. This allows for more highly refined classifying and bookmarking, which leads to more highly refined searching and displaying abilities. A graphical user interface is provided that allows a user to easily designate multiple sections of the composite document and enter and edit the data and metadata associated with the composite document.
