The Law!
• Leahy-Smith “America Invents Act” (AIA)!• Signed September 15th, 2011!• Introduces significant reforms!
– USPTO granted fee setting authority!– No more Tax Code compliance strategy
patents!– First to Invent à First Inventor to File!– Expanded Post-Grant procedures and
reviews!– And more!!
The Requirements!
• Support filing of AIA Petitions!– Inter Partes Review!– Transition program for Covered Business Methods!– Post-Grant Review !
• Collect documents!– Papers & Exhibits!– Public, private, or confidential visibility!

!!!!
The Architecture!
5!
Alfresco 4.0 Enterprise!
!• Persist Documents!
COTS Case Management Product!
!• Support Petitions Workflow!• Send Notifications!• Collect Payments!• Persist Case Metadata!• Provide Public Search!
CMIS!
Petitioners, Public
USPTO Personnel
The Constraints!
• Congressionally-mandated deadline!• First production system to use Alfresco and Case
Management COTS Product!• Case Management COTS Product limitations!
– Only supported CMIS!– Handled user registration and authentication!– Closed architecture!
6!
The Strategies!
• CMIS Only!– Single, top-level “DropZone” for Case creation!!
7!
PGR2013-00001
Cases/DropZone/
createFolder OnCreateNodePolicy PGR2013-00001
Cases/2013/PGR/00/
1. Validate uniqueness of CaseID
2. Move folder 3. Track CaseID in
attributeService 4. Create case sub-
folders with ACLs
The Strategies!
• CMIS Only!– Case-specific Drop Zones for filing documents!

PGR2013-00001 1. Move to appropriate
subfolder/rename 2. Apply caseId aspect 3. Apply ACLs based
on visibility, if necessary
The Strategies!
• Externalized User Registration/Authentication!– Trusted connection between Case Management
Product and Alfresco!

<servlet> <servlet-‐name>cmisprps</servlet-‐name> <servlet-‐class> org.apache.chemistry.opencmis.server.impl.atompub.CmisAtomPubServlet </servlet-‐class> <init-‐param> <param-‐name>callContextHandler</param-‐name> <param-‐value> gov.uspto.prps.AutoAuthCallContextHandler </param-‐value> </init-‐param> <load-‐on-‐startup>8</load-‐on-‐startup> </servlet>
The Strategies!
• Externalized User Registration/Authentication!– Alfresco users created on demand!
10!
public Map<String, String> getCallContextMap(HttpServletRequest request) { // ...extract username from HTTP request String ticket = ticketComponent.getCurrentTicket(username, true); AuthenticationUtil.runAs(new RunAsWork<NodeRef>() { @Override public NodeRef doWork() throws Exception { return personService.getPerson(username); // call has side-‐effect! } }, AuthenticationUtil.getSystemUserName()); Map<String, String> context = new HashMap<String, String>(); context.put(CallContext.USERNAME, ""); context.put(CallContext.PASSWORD, ticket); return context; }
The Strategies!
• Externalized User Registration/Authentication!– Dynamic group assignments based on
metadata provided in CMIS call!
11!
// during execution of onCreateNode policy for documents... String user = AuthenticationUtil.getFullyAuthenticatedUser(); String group = groupName(caseId, filingParty); // hides PermissionService.GROUP_PREFIX weirdness Set<String> groupMembers = authorityService .getContainedAuthorities(AuthorityType.USER, group, true); if (groupMembers == null || !groupMembers.contains(user)) { authorityService.addAuthority(group, user); }
The Strategies!
• Closed Architecture!– Folder structure reflects business view!– Content model holds key metadata!– Use CMIS!
• Expunging!• Reporting!• Auditing!• Multi-document PDF generation!
12!
The Wish List!
• Generate code from content model XML!– e.g. XJC (JAXB), wsdl2java, hbm2java!
• Support Webscripts written in any JSR 223-compliant language!
• CRUD in CMIS Query Language!• Apache Chemistry to go 1.0!• Servlet 3.0/JavaEE 6 support or URL dispatching
via Spring Web!
13!
The End!
