| You can use special search syntax listed below to combine search terms or strategically develop a search. Full documentation is provided in the Advanced Searching Techniques section of the Online Help. |
| Operator |
Syntax |
Search Example |
Sample Results |
| OR |
x or y |
specific or generic |
"In addition, there are specific or generic product claims to lamivudine salicylate and emtricitabine salicylate and their hydratesin many patents." |
|
The OR operator retrieves records that contain any or all of the search terms. For example, the search heart attack or myocardial infarction retrieves results that contain the terms heart attack, myocardial infarction or both terms; results are all inclusive. You can use the OR operator in both unqualified searches and searches applied to a specific field. |
| AND |
x and y |
generic and specific |
"The patent family listed here contains generic and specific product claims to ambrisentan and relates to the VOLIBRIS and LETAIRIS formulations of ambrisentan." |
|
The AND operator retrieves only those records that include all of the search terms. For example, the search blood pressure and stroke retrieves results that contain the term blood pressure and the term stroke together in the same record; results are exclusive of records that do not contain both of these terms.
You can use the AND operator in both unqualified searches and searches applied to a specific field. |
| NOT |
x not y |
generic not specific |
"The medicament is either a protein or polypeptide but no specific drugs are claimed" |
|
The NOT operator retrieves records that contain the first search term and excludes the second search term. For example, the search health reform not health maintenance organizations retrieves only those records that contain the term health reform but excludes the term health maintenance organizations. In this way, you can use the NOT operator to restrict results to a specific topic.
You can use the NOT operator in both unqualified searches and searches applied to a specific field. |
| Adjacency (ADJ) |
x y |
generic adj name |
"The marketed form of abacavir is the hemisulfate salt and has the generic name, abacavir sulfate." |
|
The Adjacent operator (ADJ) retrieves records with search terms next to each other.You do not need to separate search terms manually by inserting ADJ between them, because when you separate terms with a space on the command line, Ovid automatically searches for the terms adjacent to one another. For example, the search blood pressure is identical to the search blood adj pressure. |
| Defined Adjacency (ADJn) |
x ADJn y |
generic adj3 claims |
"The earliest 7 relate to WO9427979,of ImmunoPharmaceutics, and are associated with generic claims to sitaxentan." |
|
The defined adjacency operator (ADJn) retrieves records that contain search terms within a specified number (n) of words from each other in any order. To use the adjacency operator, separate your search terms with ADJ and a number from 1 to 99. For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship within five words of each other in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship of the physician to the patient. |
| Unlimited Truncation ($) |
x$ |
pro$ |
"The patent family listed here claims a dosage form comprising a proton pump inhibitor, such as dexlansoprazole, and relates to the DEXILANT formulation of dexlansoprazole."
"thrombolytic, recombinant protein, biotechnology, protein, plasminogen activator" |
|
Unlimited truncation retrieves all possible suffix variations of the root word indicated. To apply unlimited truncation to a term, type the root word or phrase followed by either of the truncation characters: $ (dollar sign) or * (asterisk). For example, in the truncated search disease*, Ovid retrieves the word disease as well as the words diseases, diseased, and more. |
| Limited Truncation ($) |
x$n |
gen$1 |
"biotechnology, gene therapy" |
|
Limited truncation specifies a maximum number of characters that may follow the root word or phrase. For example, the truncated search dog$1 retrieves results with the words dog and dogs; but it does not retrieve results with the word dogma. |
| Mandated Wildcard (#) |
xx#y |
m#n |
"The patent family listed here claims the use of letrozole in the treatment of detrusor urethral sphincter dyssynergia in men." |
|
Searching with a mandated wildcard retrieves all possible variations of a word in which the wildcard is present in the specified place. You can use it at the end of a term to limit results to only those that contain the word plus the mandated character. For example, the search dog# retrieves results that contain the word dogs, but not those that contain the word dog, effectively limiting results to only those that contain the plural form of the word. The mandated wild card character (#) is also useful for retrieving specialized plural forms of a word. For example, the search wom#n retrieves results that contain both woman and women. You can use multiple wild cards in a single query word. |
| Optional Wildcard (?) |
xx?y |
labo?r |
"A2B3 Prostaglandin Antiulcerants, G2A Labour Inducers, R6A Systemic Antihistamines" |
|
The optional wild card character (?) can be used within or at the end of a search term to substitute for one or no characters. This wild card is useful for retrieving documents with British and American word variants since it specifies that you want retrieval whether or not the extra character is present. For example, the optional wild card search colo?r retrieves results that contain the words color or colour. You can use multiple wild cards in a single query word. |
| Literal String ("") |
"x / y" |
"extended/adjusted" |
"The term of US 6730679 has been extended/adjusted by 236 days. |
| "sp" |
20050629.sp. |
"Expiry Date 20050629" |
|
Quotation marks can be used to retrieve records that contain literal strings,
when the string includes special characters, such as a forward slash (/).
Quotation marks can also be used to retrieve records that contain numbers
that may otherwise be confused for earlier searches. In the example, a
search for 3.vo would limit the string from your third search in your search
history to the volume field. By including the number in quotation marks,
the search will retrieve documents with a 3 in the volume number. |

The patent family listed here claims a dosage form comprising a proton pump inhibitor, such as
dexlansoprazole, and relates to the DEXILANT formulation of dexlansoprazole.
Country Comments
US patent US8461187 claims a dosage form comprising a proton pump inhibitor (PPI), where the PPI is
released from the dosage form as a first and a second dose. The first and second doses are released
from the dosage form as discreet pulses of the PPI separated by a period of time, where the second dose
contains at least 10% more of the PPI than the first dose, and where each of the first and second doses
comprise a sufficient amount of the PPI to raise plasma levels of thePPI to a concentration of at least 100
ng/ml.

General Comments
The patent family listed here claims a method for treating a finely divided powdered medicament, such as
formoterol in combination with budesonide.
Also claimed are agglomerates for use in the TURBUHALER breath-actuated dry powder inhaler.
This family relates to the SYMBICORT TURBUHALER formulation of formoterol in combination with budesonide.
Country Comments
Argentinian patent AR255059 is based on WO9509615 and claims a methodof treatment of a finely divided
powdered medicament having a primaryparticle size smaller than 10 mcm and poor flowing properties, to
form, in a controlled manner, agglomerates or pellets that are free flowing and that are capable of
breaking down to provide the finely divided medicament, the method comprising the steps of:
- agglomerating the powdered medicament having particle sizes of lessthan 10 mcm by feeding the
material to a screw feeder and letting thematerial pass through the screw feeder to obtain agglomerates;
- spheronizing the resulting agglomerates in order to provide agglomerates that are more spherical, more
dense and more compact than those obtained from the agglomeration process in the screw feeder; and
- sizing the agglomerates to obtain a uniform size of the final product.
Formoterol in combination with budesonide is claimed generically as the medicament.
