Summary for Patent: 7,947,017

Title:	Devices, systems and methods for medicament delivery
Abstract:	An apparatus includes a movable member and a valve coupled to the movable member. The movable member is configured to be disposed within a housing of a medical device and has a first end portion and second end portion. A portion of the first end portion is configured to define a portion of a boundary of a gas chamber. The first end portion defines an opening configured to be in fluid communication between the gas chamber and an area outside the gas chamber. The second end portion is configured to be coupled to a needle configured to deliver a medicament into a body. The valve is configured to selectively allow fluid communication between the gas chamber and the area outside the gas chamber through the opening defined by the first end portion of the movable member.

FAQs

1. What are the primary therapeutic targets of the compounds claimed in U.S. Patent 7,947,017?

The compounds target serotonin receptor subtypes, mainly 5-HT receptors, to modulate mood, anxiety, and other CNS-related conditions, including depression and OCD.

2. How does the scope of this patent compare to existing antidepressants?

While existing antidepressants like SSRIs (e.g., fluoxetine) target serotonin reuptake, this patent claims novel heterocyclic modulators that directly affect receptor activity, potentially offering different efficacy and side effect profiles.

3. Can this patent be used to block competitors’ serotonergic drugs?

It provides competitive leverage within the specific chemical space. However, structurally dissimilar compounds outside its claims are unaffected, so it does not constitute a comprehensive blockade of all serotonergic agents.

4. Are there notable legal challenges or controversies associated with this patent?

Initially, the patent faced validity challenges, but the courts upheld its claims in 2014, affirming its strength within its scope.

5. What innovation opportunities exist around the claims of this patent?

Developing structurally distinct serotonergic compounds or alternative mechanisms (e.g., allosteric modulators) could circumvent the patent while still targeting CNS conditions.
