Patent searches can produce a variety of useful information beyond the specific technologies described in the patent documents themselves.
Monitor patents to accomplish any of the following …
1 Determine the possible strategic implications of a competitor’s approach to a given problem
2 Identify potential licensing partners to help solve a particular technological problem
3 Find potential presenters for technical conferences, workshops, and symposia to be sponsored by your organization
You will find other uses as you put your imagination to work.
By way of example, here are a few results from a recent PatentStorm (www.patentstorm.us) search on "dibenzothiophene" Note the organization listed in the Assignee or Attorney field. Companies like TotalFina and Honeywell will come as no surprise. The University of Michigan, however, may not have been on your radar.

No. 10726935 filed on 12/03/2003
Abstract
A method for removing thiophene and thiophene compounds from liquid fuel includes contacting the liquid fuel with an adsorbent which preferentially adsorbs the thiophene and thiophene compounds. The adsorption takes place at a selected temperature and pressure, thereby producing a non-adsorbed component and a thiophene/thiophene compound-rich adsorbed component. The adsorbent includes either a metal or a metal cation that is adapted to form π-complexation bonds with the thiophene and/or thiophene compounds, and the preferential adsorption occurs by π-complexation. A further method includes selective removal of aromatic compounds from a mixture of aromatic and aliphatic compounds.

YOO, Jin S.
LEE, Sang-Chul
KIM, Ho Dong
Assignee
KOCAT Inc.
Abstract text
The present invention relates to a process of reducing sulfur- or nitrogen-containing compounds and producing oxygenates, and in particular to a one-pot process of reducing sulfur- or nitrogen-containing compounds and also producing oxygenates in the presence of a homogeneous catalyst such as Mn+/a first solvent or M1n+/a second solvent/M2m+/a third solvent or a mixture thereof, the process herein being useful as an excellent octane booster in the reformulated gasoline and as a cetane booster for the future oxygenated diesel in a one-pot reaction.

Assignee
Totalfinaelf France
Application
No. 10542269 filed on 01/15/2004
The invention
relates to a process for hydrotreatment of a hydrocarbon feedstock, comprising the step of carrying out in situ or ex situ sulfurization of a catalyst and hydrotreating the hydrocarbon feedstock in the presence of the catalyst wherein at least one sulfur compound may be present in the feedstock; and a process for the purification of a hydrocarbon feedstock, comprising hydrotreating the hydrocarbon feedstock in the presence of a catalyst after sulfurization of the catalyst and oxidizing desulfurization of the hydrotreated feedstock; wherein the catalyst comprises a refractory oxide support, at least one metal of the Group VIII and at least one metal of the Group VI, both in an oxidized form, and at least one sulphone or sulphoxide compound derived from a benzothiophene compound

Rohrbach, Ronald P.
Zulauf, Gary B.
Unger, Peter D.
Bause, Daniel E.
Assignee
Honeywell International Inc.
Abstract
Disclosed are fuel filters and process for removing sulfur-containing compounds from a post refinery fuel stream. In one embodiment, the disclosed process requires passing the post refinery fuel stream through a fuel filter to provide a clean fuel stream having a reduced concentration of sulfur-containing compounds relative to the post-refinery fuel stream, wherein the fuel filter comprises an adsorbent comprising an inorganic oxide having a surface acidity characterized by a pKa of less than or equal to −3.
