Release 3.33.2 (February 17, 2026)
This release contains support for batch adding and removing of part numbers in the claims and abstract, batch editing of part names, and a number of fixes and UI refinements.
Adding and Removing Part Numbers in Claims and Abstract
Rowan has added the ability to convert terms to part references and vice versa in your claims and abstract, supporting quick conversion between claims written for the US jurisdiction and claims appropriate for EPO filing, provided you have identified the appropriate terms and used them as part names in your figures.
Batch Editing Part Names and Their Plural Forms
You can now select multiple parts in your parts list and edit the part names and plural forms for all selected parts in one operation.
Other Improvements and Fixes
More autocomplete dropdown options provided for two-digit part numbers
More robust error handling during flowchart generation
Improved handling of pasted text with comments
Support for sub- and super-script text in R-group descriptions and term definitions
Improved table border style support for tables imported from Word
Expanded figure label alignment options in Drawing Tool
Release 3.32.3 (December 15, 2025)
This release is a hotfix, one that restores default functionality around the user dictionary.
RELEASE 3.32.2 (December 12, 2025)
This release contains support for electrical engineering stencils, improved support for the ST.26 standard within the sequence manager, and other fixes.
Electrical Engineering Stencils
Rowan has added stencils to support creation of circuit diagrams within the drawing tool. These include a variety of amplifiers, resistors, capacitors, grounding elements, and more, as well as improved stencil connection behaviors.
For details around the stencils, see the overview article here.
Sequence handling improvements
To finish Rowan's efforts around ST.26 compatibility, the sequence manager now addresses the following features:
Management of skipped sequences
Modification of nucleotides and amino acids, including variant sequences
Improved import and export support of ST.26 documents
Removal of ST.25 export
For details on the process, look into our article on Describing Large Molecule Sequences.
Figure tag customization
Users can customize how figure tag text is displayed within the specification, as well as how figure ranges can be displayed.
This includes being able to customize whether the software uses FIG versus Figure, and how ranges are displayed within the specification.
Other improvements and fixes
Tables - when importing from .docx files, Rowan does a better job at preserving column widths
Ability to flip and mirror stencils within the drawing tool
In the drawing tool, the parts list syncs with figure navigation again
RELEASE 3.31.1 (November 6, 2025)
This release contains improvements to the sequence manager alongside bug fixes and UI refinements.
Preparation Improvements
Sequence handling improvements
As part of an effort to shore up ST.26 compatibility within the application, Rowan's sequence manager now addresses adding and editing the following parameters:
Inventor
Applicant
Organism details for each sequence
Intentionally skipped sequences
The software now also detects of sequences with duplicate bases or amino acids, to help users catch issues either on import or during export.
Additional text justification options in the Drawing Tool
When selecting a stencil with an element label, there are now additional options for customizing label placement. There are now options to place the label around the outer perimeter of the stencil as well as within the stencil, at the top left/right and bottom left/right corners.
Compound customization
When creating molecular drawings within the ChemDraw software, Rowan is now able to inherit styling parameters from source .cdxml files. These settings include default bond length, drawing size, and letter font among other parameters.
In the Document Settings, users can upload a file with their preferred styling, and the software will render drawings with those styles moving forward.
Prosecution Improvements
Edit molecular drawings in the Response Writer
For the cases where a molecular drawing needs to be updated during prosecution, Rowan now allows users to leverage their molecular drawing program of choice to make these updates.
Other improvements and fixes
Able to customize units of measurement as part of document setup
New "Recent Files" option in the menu
Additional sorting parameters for document templates
Fixed a bug in prosecution around equations not exporting properly
Fixed in bug in preparation around text disappearing when creating R-Groups with images in the text
RELEASE 3.30.2 (September 16, 2025)
This release contains a plethora of bug fixes, functional improvements, and UI refinements including some performance improvements.
Prosecution Improvements
GenAI Functionality in Prosecution
As part of the Rowan team's push to give our users access to GenAI tools, we've brought the inline AI Chat and AI Sidebar to the prosecution module. With these features, users can now leverage their preferred AI models to help in crafting office action responses while leveraging Rowan's tools.
First-to-File Integration
Rowan is rolling out an integration with Clarivate's First-to-File service, starting within the prosecution module. This integration allows the Rowan software to link with the First-to-File widget, allowing users to fetch associated office actions and claims from the IPMS. It is the first piece of a broader initiative around meeting our users where they work.
Additional EPO drafting improvements
Line numbering on document export
An often-requested feature is the ability to have line numbering within exported documents. To that end, the ability to export a document with line numbering is now available within the File Settings, under Document Styles.
Additional phrasing settings around multi-dependent claims
Within the claim text settings now lies the ability to adjust the phrasing of multiply-dependent claims. Language can be adjusted using the most commonly found phrases to account for claims with different parent scenarios, including contiguous and noncontiguous two parent claims and ones with 3 or more contiguous or noncontiguous parent claims.
General improvements
Drawing Tool Right-Click Menu
To accelerate access to options within the drawing tool, there is now a right-click menu that triggers when on the canvas. This feature gives shortcuts to common functionality found within the drawing tool including showing and hiding the guides and grid, adding a sheet, finding parts on the canvas, and more.
Figure ranges within the main drafting window
We've heard our users loud and clear - they want to be able to use and track figure ranges like they can with claims. With this latest release, our users can now adjust figure ranges in the detailed description by clicking on a Figure label and selecting the relevant options. This changes the tagged reference to a range, similar to multi-dependent claims tags.
Part Reference Styles
There are more ways to customize part references within the Document Styles section. There continues to be support for part name + number in plain text. We have added support for a bolded part number (part 102), an italicized part number (part 102), and a bolded and italicized part number (part 102).
Other improvements and fixes
More label adjustment settings
Duplicate parts to Figure
Additional part number styling settings in the Specification
Word-style superscript and subscript toggles
Batch stencil rotation undo fixed
Drawing tool connector improvements
Find and Tag R-Groups
Now using Clarivate's Azure OpenAI endpoint instead of the OpenAI enterprise endpoint
Landing page improvements
RELEASE 3.29.0 (August 1, 2025)
This release is centered updating how Rowan performs code signing on the software along with minor bug fixes.
LLM Configuration Improvements
The user interface and backend for LLM configuration have been updated. Users are now able to add multiple instances of Azure and Portkey.AI for model access. The new interface allows for more streamlined model management. In addition, users are now able to give their models unique names within the software to allow for easy identification during selection.
Other improvements and fixes
Fixes for improved copy-paste of molecular drawings from Word documents and Biovia Draw
Additional document window styles available from the dropdown (i.e. header, footer, figure caption, heading levels 4 and 5)
Updated code signing certificates
Improved error logging for disappearing images in the drawing tool
Bulleted list level 3 uses USPTO-approved fonts
